Great — here are recommended hotels in/around Marina Bay and the Downtown area that are convenient for visiting Gardens by the Bay (short notes on why each is good, approximate distance / travel time, star level and typical price tier). I’ve included transit notes so you can see how easy it is to reach the Gardens.

Top picks (closest to Gardens by the Bay)

• Marina Bay Sands — iconic hotel with rooftop SkyPark and direct access to the Bayfront area. It sits adjacent to Gardens by the Bay (you can walk across the Helix Bridge / Bayfront pedestrian routes or use Bayfront MRT). 5-star; premium price. Good if you want direct views of the Gardens/Marina Bay and a short walk to the conservatories and Supertree Grove. (en.wikipedia.org)

• The Fullerton Bay Hotel (Marina Bay) — luxury boutique 5-star on the Marina Bay waterfront, short taxi or 10–20 minute walk to Gardens by the Bay depending on route. Great for central Marina Bay sightseeing (Merlion, Esplanade) and a quieter luxury stay. 5-star; premium price. (fullertonhotels.com)
