Activity Ideas

1) Shopping is located just one block from the Crowne Plaza
2) Hiking Trails with varied levels: 

High Peaks like this one: http://gorp.away.com/gorp/resource/statepark/ny/hik_marc.htm
Easier like this: "Cobble Hill overlooking Mirror Lake and the village of Lake Placid, this short hike off the Cobble Hill Road offers a 360-degree view of the Olympic Village and the surrounding High Peaks"
3) Tennis maybe we can set up a mini family tennis tournament!  
4) Golf is an obvious option near the hotel for anyone that plays.
5) Mountain Bike Tours - this looks SO much fun! They have road biking, touring, and mountain biking.
