The following is if you can handle local color, at least foodwise. Chinatown is an easy bus ride from your hotel, 5 to 10 minutes will do it.
If this idea sounds good, from your hotel, walk to Hill Street and go to the bus stop (same block as your hotel, don't cross the road). Take any bus, these will be any of 2, 12, 33, 147, 190. To be safe, confirm with the driver that they're going to Chinatown. Get off five stops later, this is in front of Chinatown Complex. On either side of the road are food places - your side (this is New Bridge Road), check out the side streets (Temple, Pagoda, Mosque Street, respectively) for street food. Otherwise go across to the other side of the road (this is Eu Tong Sen Street) and enter People Park Complex - it's sort of interlinked with People's Park Food Centre, which is the hawker center in the area.
If you're wandering around People's Park Complex, you will presumably pass by a few massage places. I can't make any recommendations for massage places there but I suggest that you look around at different places, and see if there's one you're comfortable with. When you're done, go to the bus stop on Eu Tong Sen in front of People's Park Complex and take any of 2, 12, 33. Check the board to make sure one of these buses call at your stop, the buses skip stops along this road. Get out at the bus stop in front of Armenian Street (Armenian Street Church here, local landmark) and cross the road back to your hotel.
If you're a museum person, there's no shortage of different museums in the general area that you can walk to from your hotel, but I'll leave that as your homework (concierge will help you with that). The other place you can walk to is Funan Plaza, which is a shopping mall for various computer products. This should be more than enough stuff to keep you well diverted for the time you're in Singapore.
