Great — here’s a practical, budget-friendly 5‑day plan that covers Riyadh (your likely start point in Saudi), Dubai, and Kuwait, plus clear travel, visa and money-saving tips. I assume you’re based in Saudi Arabia; I’m using the latest visa/flight guidance (Aug–Oct 2025) where relevant — I’ve cited sources for the key, time‑sensitive points.

Suggested trip outline (fast, low-cost loop): Riyadh → Dubai → Kuwait → Riyadh Total days: 5 (example: Day 1 depart Riyadh → Days 1–2 Dubai → Day 3 fly Dubai→Kuwait → Day 3–4 Kuwait → Day 5 fly Kuwait→Riyadh)

1. Route, flights and timing (cheap + fast)

• Sequence: Riyadh → Dubai → Kuwait → Riyadh. This minimizes backtracking and uses short direct flights between each city.
• Typical flight times:
  • Riyadh ↔ Dubai: ~2.5–3 hours (frequent daily services). (check exact schedules/price for your travel date)
  • Dubai ↔ Kuwait: ~1h40. Jazeera and several carriers operate competitive services. (jo.wego.com)
  • Kuwait ↔ Riyadh: ~1h20; low-cost/regional carriers like Jazeera run direct routes at budget fares. (jazeeraairways.com)
• Budget carriers to check (compare prices on aggregator sites): Flynas, flydubai, Air Arabia, Jazeera Airways, low‑fare options from Emirates/Kuwait Airways during sales. Book 3–6 weeks in advance for best budget fares.

2. Visas & entry (important, time-sensitive)

• Kuwait: As of Aug 2025, foreign nationals who are residents of any GCC country (including Saudi residents) with at least six months’ residency validity can obtain a tourist visa on arrival at airports/land borders — you’ll need your passport and valid Saudi residency permit. This makes short trips to Kuwait easy for GCC residents. (saudi-expatriates.com)
• Saudi Arabia (return): If you’re a Saudi resident or citizen you can return normally; if you’re visiting Saudi from abroad you may need the Saudi eVisa depending on nationality — check the official Saudi eVisa portal for your nationality and fees. (If you’re a Saudi resident this shouldn’t block your return.) (gulfnews.com)
• UAE (Dubai): Check whether you need a visa or qualify for visa-on-arrival based on your passport. GCC residents often have simplified entry rules — verify online with UAE immigration or the airline before booking.

3. Sample day-by-day itinerary (tight & budget) Day 0 (evening before / early Day 1)

• Book an early evening or overnight flight Riyadh → Dubai (arrive Day 1 morning). Day 1 — Dubai (sightseeing on a budget)
• Morning: Metro to Dubai Marina / JBR walk (cheap, scenic).
• Afternoon: Al Fahidi Historical Neighbourhood + Dubai Museum (low-cost culture).
• Evening: Dubai Mall fountain show (free) and cheap food in food courts or local shawarma places. Day 2 — Dubai (low-cost highlights)
• Morning: Abra ride across Dubai Creek (small fee) + Gold/Souq walk.
• Afternoon: Beach time at Jumeirah Public Beach (free) or rent a budget beach lounger.
• Night: Fly Dubai → Kuwait (late evening or red-eye) OR take an evening flight to Kuwait if schedules/prices suit. Day 3 — Kuwait (arrival + explore)
• Afternoon: Corniche walk, local markets, cheap seafood/shawarma.
• Evening: Souq Sharq area or Al-Mubarakiya-style markets (affordable local food). Day 4 — Kuwait (culture + quick day trips)
• Visit Kuwait Towers (iconic; low entry fee), the seafront, and any local museums. Use local buses/taxis or ride‑sharing to keep costs down.
• Late evening: Fly Kuwait → Riyadh (many short flights available); alternatively fly next morning if cheaper. Day 5 — Back in Riyadh / buffer day
• Use as travel buffer or explore Riyadh’s low-cost attractions: Masmak Fort, Al Zal market, King Abdullah Park.

4. Budget estimates (very approximate per person; adjust to your dates)

• Flights (total triangle, budget carriers): SAR 800–1,500 (or lower if you snag sales). Prices vary widely by date — book early. (jazeeraairways.com)
• Accommodation (4 nights): budget hotels / guesthouses / cheap Airbnb — SAR 120–300/night → SAR 480–1,200 total.
• Food: SAR 60–120/day (street food, food courts) → SAR 300–600.
• Local transport + small admissions: SAR 200–400.
• Estimated total (thrifty): ~SAR 1,800–3,700 per person. (Use exact flight costs and dates to refine.)

5. Money-saving tips

• Flights: Use price comparison sites and sign up for fare alerts; check mid-week departures (often cheaper). Book carry-on only to avoid baggage fees.
• Accommodation: Pick centrally located budget hotels or well-reviewed hostels/Airbnbs to reduce transport costs. In Dubai, stay near a Metro line.
• Food: Eat at local cafeterias, food courts and street vendors rather than tourist restaurants.
• Public transport: Use metros, buses, and shared taxis where available. In Dubai the Nol Card and Metro are very economical.
• Attractions: Prioritize free/cheap sights (corniches, souks, public beaches, city parks). Buy only one paid attraction (e.g., observation deck) if you want a “big” experience.
• Travel light: a single carry-on speeds you through airports and avoids checked-baggage fees.
• Multi-city search: use “multi-city” search mode when booking (Riyadh → Dubai, Dubai → Kuwait, Kuwait → Riyadh) to compare cheaper routing than three single tickets.

6. Practical safety & logistics

• Check luggage/baggage rules for low-cost carriers — carry-on limits can be strict.
• Always carry a copy/photo of your Saudi residency permit and passport (required for Kuwait visa-on-arrival).
• Buy travel insurance that covers flights and basic medical needs.
• Check COVID or health entry requirements only if airlines or governments list them (most Gulf travel is currently open, but reconfirm before departure).

7. Next steps (quick checklist)

• Pick travel dates and search multi-city fares for your chosen dates (book 3–6 weeks ahead for budget fares).
• Confirm visa requirements for your passport and residency status (esp. UAE if you’re not a GCC resident).
• Reserve 3–4 budget hotels/Airbnbs near public transport and pre-book any must-do paid attraction.
• Set fare alerts and monitor prices for 3–7 days before booking.

If you want, I can:

• Search and compare sample multi-city flight prices for specific travel dates you give (I can pull real-time fares),
• Or build a tighter day-by-day schedule with exact flight times and suggested budget hotels per city.

Which would you prefer: (A) I compare flight prices for specific dates you have in mind, or (B) I build this itinerary with sample bookings (flights + budget hotels) for a chosen 5‑day window?
