We booked a 2-bedroom suite through tsadventure.com for my sister-in-law's bachelorette party last August. It's a nice place to stay and there is shuttle service. A cab fare to the strip is not bad either. It's nice having a full kitchen and the master bedroom was wonderful.
If you're not a timeshare owner, I would book with tsadventure.com.
However, if you decide you would like buy a timeshare with Wyndham please book something with my brother since he works for them. You can find him at the Harrah's Hotel Wyndham Timeshare Preview Center.
