Where to train in Bangkok etc on family vacation?

Hi guys it’s been a desire of mine to train in Thailand for about a decade or so. My wife and I have been discussing going to Bangkok for a vacation trip at some point. She doesn’t train at all. Any recommendations on how or where I could train in the morning/middle part of the day to still be back in time to go do activities for the rest day with my wife/family? Maybe somewhere just doing some private lessons would be best?
