there plenty of families that vacation in SHV an unless ur out and about at night ( which i doubt with a 4 years old) whats the bg deal
The independence is great ( although not cheap) , private beach, look at the Sokha hotel as well http://www.sokhahotels.com/sihanoukville/
As far as pattaya goes, same, lots of entertainment/resorts for families with kids
SHV wishes it could be the Pattaya of Cambodia LOL
Patttaya gets more visitors than all of Cambodia!!
but it wont ever happen
To the op, i assume u wouldn't take ur kid to Patong as well?
