I'm traveling to CDG for the first time tomorrow on US and land in T-1. I'm meeting a colleague who is flying AA in T-2. My question is are the 2 terminals connect that I can walk to T-2 or do I have to take a shuttle etc.?

The other question I have is what lounge you would recommend for a *A Gold member. I'll have a little over an hour to kill and would like to spend it in a club rather than aimlessly wondering around the airport. I know there's a UA, LH and Swiss lounge in T-1. Which would you recommend? Thanks!
