I'm in Australia right now and don't have all my links with me here. The ground "packages" being offered by the official U.S. provider run $7,000-10,000 a week. I can post when I get home over the weekend.
We're hoping that USA Swimming or USA Olympic Committee comes along with a family/friends package like they did for Sydney, but have not received anything yet (it was $US300 a night there).
If that doesn't pan out, the miles for award tickets go back into the account and I won't go. All the contacts with "friends of friends" in Athens have not worked out.
I'm going (if I go) with the Coughlins to see Natalie swim (will also be at Olympic Trials in Long Beach in July). Are you going to support a particular athlete?
