Based on an 8am scheduled opening, should we plan to arrive at the garage at 6:30am?
normally, the garage parking lot opens one hour before the park is opened.
official opening time of 9, that is.
i'm not sure what time to tell you to be there now.
with the parks opening at 8 and the garage at 7, it wouldn't be a bad idea to be there very early.
i know you might end up sitting in line for a lengthy time, but if the parks are packed, it would be well worth it in the long run. stop along the way and buy a box of donuts to eat in the car while waiting.
crowds usually start to grow around the 10:30-11:00 time period in regular season.
with the holiday season, i'm sure many will want to be at the parks early to avoid the early crowds that will be there.
if you can start doing the rides at 8:00, you will be able to hit a lot of what you want to do within the first 2 hours.
once the people come and crowds begin, there will be long waits for about everything.
when i stayed off site, the earliest i got to the garage parking lot was at 7:30 in the regular season.
hopefully, some one will be able to answer your question better than i have.
i am not sure what to tell you about arriving at 6:30
if it were me, i know i would but i am anal on those things.
