Budget 2 months travel Thailand Family of 5

For those of you wondering how much and how we did it (basically, for people curious like myself)... The total came to $13,500 Which included RT tickets from LAX to Bangkok, two one way flights in Thailand, all food, hotels, allowances, trinkets for 63 days, elephant riding and an 11 day sailing trip plus a very expensive hotel in Beijing! RT tickets were purchased back in July after a better than normal house flip, in country flights were used with frequent flyer miles and the rest we paid for out of our monthly income from rentals since we don't have any bills at home currently. We sometimes were kinda broke traveling and other times ate well. We always had an air con room which is more than we did the last time in Thailand. Our hotels were on average about $33/night and only two cockroaches were seen (thank you cute little geckos). Would I do it again, for sure. It was phenominal.
