If you want it you check every hour. First thing when you get up and late at night too.
The cancellations come on and you need grab it.
Or you go stand on line for line for the lounge as a last resort. I had a friend go the other day they only waited 30 minutes. They expected to be waiting several hours. Absolute worst case you are in line 4 hours for the lounge. I wouldn't do it.
There is a chance though you won't get reservations, but at a min you need try at least 3 or 4 times a day right up until the day you leave. With 64 days you have time, I am betting you will have one by 40 days. At least I'll cross my fingers for you.
We wanted Be My Guest at time it was impossible to get. I literally made my trip around the day I could get and had to re-book plane and all, at that time for me no big deal, for most it would be.
A hint that worked for me. Take any reservation they have, even if it's the wrong day. Then after keep trying to change the reservation date and time for the next couple weeks then get a new one. One time for me they were all sold out, but once I had a date booked all of sudden modified dates showed that not show before I had a reservation. I am not sure if they do that anymore or if now you would need cancel to re-book, but back than that trick worked a few times for me. The last time I tried and that worked for me at a couple years ago.
I once snagged a reservation last day of our trip too so it happens. Is that all worth it to you is the question.
I do have an AP since 2016, so I am not sure how that effects what I did or do compared to you.
