Inquiry Submission By Maggie L

We are going to Cambodia for 3 weeks that will include 2 nights on arrival in phomn penh then maybe 5/6 nights Siam reap and free time built in to travel elsewhere. We want a week on the beach but like some nightlife but not crazy times! I have read that Sihanoukville is not that nice any recommendations or current info would be good. Also should we consider Laos for a week?
