Sheddie,

You can currently buy a ticket/hotel combo from RG travel via the RG website. I did this for a night session, hotel for one night, and a ticket for the following day, just to be sure I'd be able to get on the show courts at some point

I didn't manage to get any tickets in the initial sales queue last year but did get some in the resale - it's like some sort of weird game checking all the time on the phone for tickets coming up, and seeing if you can be fast enough to buy them (good job I'm only working part-time). Don't know if the new system will make it any easier wrt this. Putting tickets back into resale is straightforward, although you lose 10% of the face value.

I did the lowest level hospitality under Suzanne Lenglen for a day session last year which was fine - would've been ok value if I could drink and eat lots I guess (but I can't and would rather watch the tennis) - free bars and lots of canape style food.

Towards the end of the second week, ground passes will get you access to Suzanne Lenglen with a big(ish) screen so you can watch the semis from Chatrier, and you can watch the veterans dubs here too. 

There didn't seem to be much availability from secondary sellers on-line or touts last year, possibly because the tickets were all digital (phone) for the first time and ID got checked as often as not when you entered the grounds, to see if it all matched up.

All said, I had a great week (the 2nd sunny week, rather than the wet and grim 1st week).

Good luck
