have you tried availing of some travel insurance deals? how did it go? what are some of the deals you purchased? besides the medical insurance (which is often covered by one's credit card), loss baggage/travel documents insurance, what are other must-buy deals? let's say i'm just going to visit singapore for some tours--no extreme activity involved--but just eating out, shopping and going to zoos, parks and museums, what travel insurance deals should i consider availing? thanks..
