Greek Vacation 

When your girlfriend/wife/boo/mistress/FWB/etc whom isn't a fan of anal sex (greek) gives it up either after you do something exceedingly nice, she is ridiculously drunk, or looking to experiment. Since this doesn't happen very often or takes awhile to work up to, it is like a cruise/trip to those ancient isles in the Mediterranean.

Guy: I can't believe it, my girl agreed to go on a Greek Vacation last night!
Other Guy: Incredible! Was it difficult getting into port?
Guy: You know I am an experienced captain, it took a few tries, but after some maneuvering my vessel just slid right in.

American Greed Vacation 

This is the type of vacation that rich people take. They do not go to see the sights of the place they are visiting but to "relax" (except maybe to golf) and spend most of the vacation stuffing their faces with fancy food or drinking gallons of wine and lounging around the hotel or possibly the beach or pool. Generally the kinds of people who go to the same place all the time and have no appreciation for what a real vacation is.

When you go to Hawaii you see a lot of people in the resort areas on American Greed Vacations.
