looking for some feedback. taking the family (twin 5 year old girls, 10 year old boy, wife) to Asia for the first time. kids are pretty good travelers, they'd flown to south america several times, and been on very long road trips. son has flown to europe several times. 7 days in singapore, pretty well planned. 8 days in thailand. two options 1. 2 days in bangkok, then night train to chaing mai, 3 day elephant trek one day in the city, night train back to bankgkok, another 2 days in bangkok. 2. 2 days in bangkok, then 5 days on an island (Koh Chang) where we can do a 3 hour elephant ride, and spend most of the time on the beach, then 1 day in bangkok. what are your thoughts on the two options? I love the idea of a 3 day elephant trek in the jungle with the kids. the beach sounds good, too, but there are beaches everywhere.
