Thanks for the feedback!!
I have the SLS booked as of now. I have read that others have had an upgrade to a 2-br suite at the W though. This could be a deal breaker; since some other friends may be able to join. But i dont think im comfortable risking it for a check in experience.
Sounds like the SLS is closer to some action (restos/bars) and the rooms sounds like they are great.
So unless someones pipes up with a convincing argument for the W. SLS it is!
Thanks again
