Wow, Las Vegas and Florida in the same month and celebrating a 21st birthday? Too cool. Your options for the birthday are endless at the Walt Disney World Resort. I went to Disneyland on my 21st and had the best birthday ever. We always enjoyed walking the World Showcase at
Epcot. There you can visit and experience 11 different countries from Norway to Mexico and beyond. My wife and I enjoy tasting the beers and mixed drinks from each country. It's a interesting way to see the world. As for golf, Disney has a great offer called 9 by 11 a.m. Here is the link,
Walt Disney World Golf Special Offer. You can enjoy some of the most beautiful golf links in Florida and still have time to enjoy the parks. If you want to stay at a Disney resort, a great place to start is at
Disney Vacation Planning DVD. This DVD will provide you with all of the resort options to fit all needs and budgets. You are going to have so much fun.
Now as for Las Vegas, my advice is to pace yourself and bring sunscreen!
Have fun.
