Edgewater would be a great choice for your vacation. It's a large enough resort to still feel exclusive and private even though it's basically in the heart of the strip.
They've got several pools, including the huge lagoon pool... tiki bars, restaurants, tennis, golf, spa... the works!
You'll probably save money through VRBO.com or private owner...but, Edgewater runs package specials form time to time as well, which can be a good value.
Go to
Edgewater's website and look at their packages... they have golf, tennis and spa packages available now... and sign up for their e-deals... I hear they have a newsletter going out soon that may have some specials in it...
