If you stay at the Wynn you can walk to connections.
The tram is BS IMO... I've ridden it, but most hotels you have to walk a mile just to get on, besides the Hilton.
Cabs cost more, but are fast.
Check all the deals, look at hotel websites, looks at booking your complete stay and airfare with hotel.
The Hilton is not bad to stay at, it was nice to be onsite. But you can find screaming deals.
But truth is, last time I went I made a vacation out of it. We stayed at the other end of the strip and visited the trade show for a few hrs.
Hell, I might come to connections this year I think it has been 3 years.
If I come alone, I'll stay somewhere like excalibur.
