Thanks heaps
Yankeeflyer and
Sinoed09!
The stay's for the 11-13th April (checkout on 13th, so nights of 11th and 12th). That's a Monday - Wednesday.
How 'big' we need is relative, but over 1,000 sqft would really clinch the LAS 'high-roller' feel, minus the risk/comp-ing, especially as we're pretty crap on the tables...
(I saw some of those buy 2 get 1 free, but we'll be halfway across the Pacific by the time the third night comes around, so that's unfortunate!)
If the Cosmo ran any promos I'd be all over that in a flash. I heard the larger rooms at Aria are also good, so they are getting more of a consideration now (will be doing my research on that property seriously in a few hours)
