Here are romantic hotel options right on or a short walk from the Marina Bay waterfront in Singapore, with a short note on what makes each good for couples and how close they are to the bay.

Top picks (waterfront or immediate Marina Bay area)

• Marina Bay Sands — iconic rooftop infinity pool, celebrity-chef restaurants and SkyPark views that are famously romantic at sunset and after dark. Located directly on Marina Bay (Bayfront). (singapore.jawa.media)
• The Fullerton Bay Hotel Singapore — intimate, waterfront boutique feel with rooms that open onto Marina Bay views, romantic dining and easy access to the Marina Promenade and Merlion Park. Right on the bay. (thehospitalitydaily.com)
• The Fullerton Hotel Singapore — grand, heritage property on the Marina Promenade with elegant rooms, fine-dining options and a classic romantic atmosphere; immediate waterfront access. (singapore.jawa.media)
• The Ritz‑Carlton, Millenia Singapore — luxury rooms with panoramic Marina Bay and city views, acclaimed spa and fine dining — a short walk to the waterfront. (en.wikipedia.org)
• Mandarin Oriental, Singapore — large luxury hotel on the Marina Bay/Marina Centre front, known for spacious rooms with skyline/bay views and a well-regarded spa and restaurants — very close to the bay. (en.wikipedia.org)

Other romantic choices a short walk or short drive from Marina Bay

• Pan Pacific Singapore — modern luxury with bay-facing rooms, couples’ dining options, and convenient access to Marina Square/Gardens by the Bay (short walk/drive). (holidaysforcouples.travel)
• JW Marriott / Conrad / Swissôtel The Stamford area hotels (Raffles Place / City Hall cluster) — several luxury properties near the Marina waterfront offering suites, rooftop bars and romantic dining within a 10–20 minute walk. (cluster reference to downtown hotels close to Marina Bay). (thetimes.co.uk)
• Hotel Fort Canning / boutique options nearby — for couples who prefer a quieter boutique vibe but still want to be near Marina Bay’s attractions (short taxi or 10–15 minute walk depending on property). (thetimes.co.uk)

Quick planning tips for a romantic stay

• Book a bay-view or SkyPark-facing room for sunset and night skyline views (Marina Bay Sands, Fullerton Bay, Ritz‑Carlton and Mandarin Oriental all offer these). (singapore.jawa.media)
• Look for special packages: many hotels offer “romance,” “honeymoon,” or couples’ spa/dinner packages — check the hotel’s offers page before booking. (thehospitalitydaily.com)
• Consider adding a private sunset cruise or a Gardens by the Bay evening visit (Supertree light show) to the itinerary — both are popular romantic activities around Marina Bay. (holidaysforcouples.travel)

If you’d like, I can:

• Compare room types, approximate price ranges, and whether each hotel currently has romance/honeymoon packages (I’ll look up live rates and offers for your travel dates), or
• Recommend a single best choice depending on budget and style (iconic view, intimate boutique, historic luxury, etc.).

Which would you prefer? (If you want price/availability or a booking recommendation, tell me your travel dates and budget and I’ll check current offers.)
