It's a good idea to mention the fact that you're a senior when you first make your travel reservations, because almost all major airlines offer discounts for seniors. In Singapore you'll find very few hotels that offer such discounts; however, virtually every attraction with an entrance fee offers a special discounted rate, and some tour companies will quote you a better rate as well.
Upon request, the STB can also help plan your trip, and can offer its own advice for senior travelers. Regarding this service, here's my advice: If you work out your itinerary with the help of STB, make sure you're firm about time constraints. Many of the tours and daily itineraries are rushed, with little time for a rest here and there. A common complaint is exhaustion by the end of just 1 day. In the heat, this is not only uncomfortable, but dangerous as well.
