[QUOTE=BananaBoi;2065410]As Natty says, never take a girl to Phnom Penh. You're going to kick yourself. Now if Siem Reap or Sihanoukville are your destination then maybe if the price is free or cheap. Sihanoukville is a decent place to bring a girl you really like but you're better off meeting a nice Khmer girl and take her.
FYI Cambodia is not overseas from Thailand.[/QUOTE]Call me a romantic but I think Sammy should take the girl with him. Sure it happens after a day or two when you've shagged your brains out, told her all your jokes suddenly the conversation dries up and she spends most of the time on her phone. But this could be the love of his life but he won't know unless he tries.
On cost, depends on the policy of the shop where she works whether there are penalties attached to her taking leave. There may not be. Regarding her end here I feel he will get some idea on how she is feeling about him. If she asks for anything in excess of say 10000 for the 5 days I would suggest the trip is more business as usual for her and may not the romantic getaway he imagines. But what the hell go for it champ and enjoy.
