DH & I enjoyed both bfast and lunch on the same day. PPO bfast 8:15 in the dark room (room was full by 8:30). After bfast walked on 7DMT then rode PP with no wait at all.
Enjoyed touring and used our 3 FPs before returning for lunch at 1:00, this time we selected the main dining hall. After lunch saw the parade and was able to book 4th, 5th, etc FP's.
This was during late August and we were on the DP. A great use of QS credits IMO. Had we not had the DP, probably would have chosen one or the other.
If you want to do both meals, by all means, keep those hard to come by reservations and enjoy!
