Yes, mixed reviews indeed. We have probably been spoiled by our experience at the Australian Open and Indian Wells, both of which offer lots of open space. It feels like Roland Garros is too crowded---they admit too many people for the space, so it is difficult to move around. And because of extra security ( 2 layers, with wand checks, bag check, and pat-down) it took us 2 hours to get in the first day. Fortunately we had good seats on Court 1 and as long as we stayed there it was fine. Getting in to Courts 2-18 was impossible, with long queues.
Our second day was totally different---we had a VIP pass to a special entrance as we were invited by a friend to sit in the player's box with his family. No lines at all. He played Stan Wawrinka in one of the main stadiums, and we were court side. But after that match we had to leave and face the crowds again.
