I am planning on traveling to Thailand in August for 4 weeks. I originally planned to spend 2 weeks in the north and then 2 weeks in the south but after hearing good things about Vietnam and Cambodia I now want to try and fit them in as well.
I was thinking about spending a few days in Bangkok then fly out to Vietnam and spend week traveling through before crossing to Cambodia for another week. I would then probably catch a flight back to Bangkok before heading to the islands in the south for remaining duration of my trip.
Does this sound possible or am trying to cram too much in short time. Also what places do you recommend and what activities do you suggest.
