We'll be in BKK, then flying to BEI, Hanoi and returning to BKK, staying at the same hotel. I plan to ask the hotel if we can leave some of our luggage there while we travel since we're coming back there, but if they don't allow it, is there luggage storage at the airport? Any suggestions would be appreciated

Yes there is and its cheap. We used it but my memory is foggy on the details. I know some of the other experts on this forum will weigh in on the details.

If you can leave your luggage at your hotel, that is best (and usually cheapest). At the airport, the rates are 70 baht per piece per day. I've done both at various times. Often the hotel won't charge you.

but I agree with kathie if returning to same hotel just laeve it there its more convienant and they don't always charge

Thanks everyone!
