Me and my husband are traveling to Bangkok, Thailand for a wedding and will be staying at Anantara Riverside Resort. We will be busy in wedding for 2 days but we do have a day free for ourselves. I would like to know what would be best to do in a day in bangkok? I am planning on a day tour to pattaya. Will that be worth? Any best tours there? Or should we do something else. Is there any other beach/island we should visit rather than pattaya?
