Nice — here’s a practical, budget-focused 5‑day plan to visit Dubai → Kuwait City → Riyadh from Qatar (or the Gulf region). I’ll give a sample day-by-day itinerary, low-cost transport options, money-saving tips, and rough cost estimates plus the important entry/visa reminders. Note: flight schedules and visa rules change, so check live prices and official visa pages before booking.

Key facts you should check first

• Direct flights between Dubai and Kuwait are ~1h40–1h55 and operated by carriers including Emirates, flydubai, Jazeera, Kuwait Airways. (wego.qa)
• Direct flights Kuwait → Riyadh are short (about 1h10–1h25) with options like Saudia, Jazeera, Kuwait Airways and low‑cost carriers on the route. (wego.com)
• A GCC “unified” tourist visa (covering multiple Gulf states) has been announced/planned — this may simplify multi‑country travel in the near future, but it wasn’t universally in effect when the sources were published, so verify current status for your nationality before booking. (cntraveler.com)

Sample 5‑day compressed itinerary (fast pace)

• Day 0 (evening before trip, optional): Fly from Qatar → Dubai (arrive evening). Stay near metro for cheap transfers.
• Day 1 — Dubai (full day): Morning: Dubai Mall & Burj Khalifa area (free to walk the promenade; Burj Khalifa observation decks are paid). Afternoon: cheap Dhow cruise or Marina walk; evening: explore Global Village (seasonal) or inexpensive local eateries in Al Karama.
• Day 2 — Dubai → Kuwait: Early flight to Kuwait (1.5–2 hr). Afternoon: Kuwait City corniche, Kuwait Towers (photo stop), Souq Al-Mubarakiya for budget food and souvenirs. Overnight in Kuwait City.
• Day 3 — Kuwait → Riyadh: Morning/early midday flight to Riyadh (about 1.2 hr). Afternoon: Masmak Fort, Al Batha or local souqs; evening: try budget Saudi restaurants or food courts in malls.
• Day 4 — Riyadh (full day): Visit Diriyah (UNESCO area/At‑Turaif) if open/affordable, Kingdom Centre (viewpoint is paid), walk in local neighbourhoods. Night flight or late evening stay depending on return plan.
• Day 5 — Return to Qatar (fly from Riyadh) or extend if preferred.

How to travel cheap between cities

• Use low‑cost or regional carriers: flydubai, Jazeera Airways, Air Arabia, low‑fare Saudia/Jazeera/Kuwait Airways services. Book one month+ ahead for best fares and check mid‑week flights for lower prices. (apnews.com)
• Keep flights short and early/late to save on fares; book carry‑on only to avoid baggage fees.

Budgeting — rough estimates per person (very approximate; check live prices)

• Flights (three short regional legs total): budget carriers can be USD 60–180 per one‑way leg depending on timing. For planning assume about USD 300–600 total for inter‑city flights if you pick budget options and book early. (Verify with flight search/airlines.) (flydubai.com)
• Accommodation: budget hotels/hostels / guesthouses near central areas: expect USD 25–70/night depending on city and season. (Dubai higher; Riyadh & Kuwait can be cheaper). Assume ~USD 40/night average → 4 nights ≈ USD 160.
• Food & local transport: USD 20–45/day if you eat street/food‑court meals and use public transit/ride‑shares → ~USD 100–225.
• Attractions/entry fees: USD 0–70 depending on paid viewpoints (Burj Khalifa, Diriyah, museums).
• Total low‑end estimate: roughly USD 600–1,100 per person (very approximate). I recommend checking live flight + hotel bundles for discounts.

Money-saving tips

• Fly midweek and book early (4+ weeks) for best fares. Use fare alerts and flexible dates.
• Stay near metro/major bus stops: Dubai Metro, Kuwait City bus routes/taxis, Riyadh metro stations (or central taxi hubs) to cut transfer costs.
• Carry just a carry‑on to avoid baggage fees on budget carriers.
• Eat where locals eat: food courts, street stalls, local shawarma/falafel places are much cheaper than tourist restaurants.
• Use city passes only if you plan many paid attractions; often walking + a few paid highlights is cheaper.
• Consider multi‑city search (book Dubai→Kuwait→Riyadh as separate legs) and compare with round-trip + separate ticket mixes — sometimes booking separate budget one‑ways is cheaper.

Visas & entry (very important)

• Visa rules vary by nationality and are updated frequently. Before booking, check official government/embassy sites for UAE, Kuwait and Saudi Arabia for your passport. The GCC unified visa may be introduced but confirm if it applies to your nationality and whether it’s active for travel dates. (cntraveler.com)
• Saudi Arabia issues tourist e‑visas to many nationalities online; the UAE and Kuwait also have varying visa‑on‑arrival or e‑visa options depending on passport. Don’t assume visa‑free access — verify. (I can look up visa requirements for your specific passport if you want.)

Logistics and timing tips

• Airport transfer: use public transport where possible (Dubai Metro from DXB; buses/taxis in Kuwait; Riyadh has taxis+ride‑shares). Allow 2–3 hours at airports for check‑in/immigration on international legs.
• Pack light and include a universal plug, photocopies of passport/visa, and any required health documents.
• Dress respectfully in Saudi Arabia and more conservatively in public places (women should check local rules for dress in Saudi and Kuwait).
