Here is a link to the tournament site (I hope it works - 1st time posting a link). If it is like last year, parking is along Lagoon road and in some lots just off Lagoon road. The skiing is on the north end of the lagoon. Last year, I parked along Lincoln Memorial Drive during my lunch on Friday and watched for a while before heading back to work. When we came back Saturday, we parked on Lagoon. We stayed several hours. We got there early enough to just walk up by the lagoon and pick a spot.
