Hi my 86 year old father in law is planning his first overseas trip with his friend, to make sure everything runs smoothly we have decided to go with them. They had originally planned to fly to London with only a short stopover in Singapore but I think it will be nice for them to have a look around Singapore. Can anyone suggest any suitable tours for people with limited mobility? Also with the Singapore stopover package would any of the inclusions be suitable? Thanks in advance!
