My fiance and I are trying to plan our honeymoon to Thailand. We are flying into Bangkok (on miles, thanks to some great advice from folks on here), and then we'd like to go to Siem Reap and then a beach near Phuket. Only hitch is that the flights to and from those places are super expensive. Do you have any suggestions as to where I might be able to cash in American Express Rewards in order to make this "internal" trip more feasible? I have 500,000 rewards points. Thanks!
