The current problem is that the tier system at DHS is horrendous. I think Disney anticipated such overwhelming crowds for GE that they thought MFSR would be in a category apart, beyond the popularity of FOP, SDD, etc., so it just wouldn`t work with fast pass. That is clearly not the case. So what we have is a mess at DHS: an almost useless FP system there, considering that FP is supposed to be an ADVANCE reservation system for attractions. As it is, we can get one useful fast pass, and two quasi-useless ones.
If MFSR was on the tier system, they could have SR, SDD and AS2 as Tier One, and TSM, RnR, TOT and everything else as Tier 2. See, that would actually make sense. As it is, virtually everyone pre-books SDD as their Tier One choice, so that one is even harder to get now. It would be a lot easier to pre-plan your day at DHS if you could also get a Tier Two that was useful. That`s the way it was when TSL opened last year, and it worked great.
