I will arrive at BKK on Friday Nov 13 around noon, and don't leave until Monday Nov 16 very early. I am seeking ideas for a weekend trip if I want to leave BKK. Will be with a friend. We were going to go to Luang Prabang but all flights seem sold out. Am i looking wrong?

Any other easy weekend trips to Laos, Thailand, other nearby flight or car destination come to mind? If not - a weekend of R and R in Bangkok is not too bad...Thx
