it depends on where you really want to go. Most females like Europe. I heard a lot of my female friends wanted to visit France or Spain or Greece. You know, the romantic places and stuff. It also depends on who you vecation with. If you going with your boyfriend, it's best to sit together and asked him where he wanted to go. I am a single guy but if I have a gf, i really dont care where i go with her as long as Im with her cus I know we are going to have a blast. Females are more into the descibtion of the place and males are more the relaxation of the place. A tropical paradice is a great relaxing place for both sexes. Example Hawaii, Cancoon, or any other small islands. If you live on the east coast, most will want to be in the west coast preferrably Southern California where they always have nice weather. Since you dont care about the cost of the trip, you should first take a Carnival cruise to an island and get yourself a really nice hotel with massages and stuff. People take vecation to get away from their busy life so try not to bring your cell phone and if you do, dont really answer it that much. You also can check out the wonders of the world like maybe the parymids or the stone hench if you're a history buff. The corners of the United States are great also like Washington area have great sceneries and southern cali like i said before. You can check out New York with the NYC or checking out the Niagra Falls. and Florida like Miami beach or the Key West. So far all of those ideas I gave you are the things I want to do in the future. I hope I can do it with a partner someday because it's more fun that way.
If you want a good-quality memory-making trip, I suggest the La Valencia Hotel in La Jolla, California. I've been there before and I can promise that you will not be dissapointed. I can't get to prices right now, but fish around their website and see if you like it.
I also suggest the Lago Mar Resort & Club in Fort Lauderdale, Florida. I went there for spring break of '08 and you will be so satisfied. I think that per night, it's somewhere in the $300s but I could be wrong. Surf their website and see what you can find.
