What are you trying to get? Sure, you won't be able to get into the top 5 or maybe the top ten but you should be able to get some good ressies...
This is only a rumor but others on this site have stated that Disney opens up a small amount of tables periodically at the most popular places. (le cellier, mama' melroses, o'hana, etc.) If you are a morning person, try logging on to the computer at 6:00am est for a couple of days.
My 90 day mark was earlier this week. I got an ADR for the first time in 3 years at Le Celler at 6:00am on my 90th day out.
Regardless, you still have some good choices out there.
