I would say 10 minute advantage to Wynn vs Encore
Its pretty easy to head over to Palazzo from Wynn Casino floor, but not sure how far the Palazzo shops door is to the conference area. Probably not so close.
But if you have Encore for a firm $100.00 a night with the 33.33$ daily credit that is the best deal of 2011 I have seen so far for Wynncore
I just checked Orbitz and the resort credit is not included. Still a great rate though. Valid for 3 night stays and good until April 1st. It has me thinking....
