Thanks for the help and detailed info CanadaDH.
In the end, my options dwindled on room availability, so I just went with the Lakeview Gold room under the FHR promo. We are planning on skiing and being outside lots, so a bigger room isnt a big draw for us. This way we get the choice of where to have breakfast and can chill in the lounge if we want, use the $100 FB credit for cocktails and ski on our last day before heading home in the afternoon after a late checkout.
For anyone else looking, the Amex FHR 4 for 3 rate is pretty much identical to what the AAA rate would be over 4 days.
Really looking forward to the last minute opportunity to get away and ski without our kids ;-)
