Here are the few I've stayed at in the past:
Venetian --> pricey, beautiful, newer and different from the the other hotels. Great classy place to go with wife/gf. Room was larger than the average rooms at Wynn or Caesars and had 3 tvs.
Wynn --> pricest of the three and it was alright; new
Caesars --> nice place; same category as Venetian but prefer Venetian
The crowd is good at all three but the XS club at Wynn and Tao at Venetian were awesome. Make sure u go2 Tao

haha
Flew out of Bellingham all times(Allegiant airlines); no problems and cheap! Direct flights
