Where to next?

Well today I got a letter in the mail from Delta Skymiles. It says that I have a balance of 17,374 expiring mileage. I must use the miles or they will go to waste. The only problem is...where should I go? Well and one more small problem, where can I go on 17,374 miles? I was thinking that I might take a nice beach trip to Hawaii. Or maybe a city trip to D.C. I just don't know.
