Check to see if tourists from your mystery country can actually visit Singapore. This virus thing is screwing up a lot of normal tourist visits.

Sentona island and the S.E.A Acquarium might be the best choice.

Hello,
Best places to visit in Singapore are:
Gardens by the way
Universal Studios
Sentosa Island
Singapore Flyer

Singapore Zoo

Besides the Gardens by the Bay, suggest the free Singapore Botanic Gardens. Don't miss its National Orchid Garden, which has a small admission fee.
