it's definetely not a "not to be missed" event. is it cool and exciting to see, yes, but not the most critical thing to see through the career or even just freshmen year.
the parade is in the morning, and freshmen will get a couple hours after the parade to see family/friends who visit. It's not a long time, but it's always awesome to see loved ones. My mom "suprsied" me in a way by coming out (she wrote me during BCT and told me about a week out) and it was nice to have her bring photos, my phone, etc that i didn't think i'd get until parent's weekend, as well as getting to see her for a couple hours.
a couple options here. the first is a taxi between the airports and the hotel. from the hotel, you could either take another taxi, or you could hope to find someone else at the hotel who's also going to watch and try to bum a ride. I would recommend talking to people on here or the parent's site and try to find someone for this friend to "tag-a-long" with to get rides from the airport and from the hotel. If you know people in the area that obviously helps. I'm sure they'll be enough people going that you'd be able to find someone to get rides with and split some gas money with them.
