I'm planning on an extended trip to Thailand and Vietnam Feb '27.  My focus will be Bangkok and Phuket to start.
I'd like to know what I'm getting into before getting over there, hence, I'd like to make reservations through a high-end agency for overnight engagements.  My brief search didn't come up with anything I'd be confident in pursuing.  Any advice to point me in the right direction will be appreciated! Thx
