There are only few interesting places. You have to take about four hours city bus from the airport or the expensive private taxi.
The local food is just fair.
I personally enjoyed walking around in the Water Town (Ancient Town) with my wife. The scenery was impressive to me, and i loved to take some photo shots here and there.
Meanwhile, i would think that the entrance fee is too high.
Taxi drivers are crazy - never want to run the meter when you go to the airport because they want to charge you an extra 40% in the flat rate and then not give you a receipt.
If you do get a receipt, it's probably fake. Other people were nice, but every single taxi driver we used was troublesome.
