Re: ur Honeymoon destinations
As for paying it--every situation is different. You can lessen expenses by searching for deals on-line and most importantly going in an off-season. The plane tickets go down about 50% and the hotel rates are better (you are more likely to find specials like "stay 2 nights and get the third free etc etc). If you are a budget minded couple---It helps choosing a destination where the daily expenses are cheaper.
Islands tend to have more expensive meals and a lot of time you are at the resort and need to have many meals there. and yes they can be crazy expensive like a New Years Buffet with a 1/2 hour dance performance by locals for $1000!!!
Europe or the Far East would be a lot cheaper hotel/food wise than Fiji, Tahiti, Seyshelles, etc etc
