Why though? I wouldn't. If my options at DHS wereThat could happen, I doubt it will often. Most people are going to pick something for close to when they are going to the park. I don't think most people will book something if the time available is not til late afternoon.
SDD at 7pm
TOT at 12
RNRC at 11
SWGE at 11
TSMM, Alien, and ST and anything else before 11
I would be grabbing SDD at 7pm and be able to pick my next selection at 11am just like all the other good options. It's my only chance to skip the SDD line and I would think at 11am I would still have a shot at one of the other good rides. (assuming a 9am opening)
