[QUOTE=buzznwoodysmom;2515872]It is very hard to get a tier 1 day of. Not impossible, but most of them are no longer available day of. I would suggest booking all 3 per day then seeing what else you can get once those are used or the time has expired.

That depends on what day and time of year you go. We were just at Epcot on Wednesday and we used our 3rd around noon. All the tier 1 attractions were available, and not later at night, they were good times. We rolled right into Test Track.
On Thursday we did MK, and used out 3rd for Pan around 2, we could have got FPs for everything except 7DMT, All the other mountains were still available.
