We usually go in Sept. and they no longer offer EMH.

That being said we go without a plan, really. Last year we did TL and BB (separate days, of course). We get there a little before opening. (they'll be a line) and then pick out a good spot to set up as base. Oh, first we grab a free life vest to use for DD8 and sometimes a locker. If it's really busy when you go, grab your spot first (I like the ones with covers, just in case it rains

) and then get life vests if needed, or a locker.
We like to do Crushin' Gusher at TL first off (Yeah DD8 is tall enough to ride this year!

).
Since you are off-site then I would definitely pick a non-EMH day to go. Less crowded, I'm sure. It looks like only BB is open early, on only on the 7th and 14th, so I would avoid those days. If you are going in the a.m. and aren't staying all day, then you may be okay going during EMH pm at TL on 2nd, 9th, and 16th. Okay I just looked at the calendar and TL is open late on Saturday-I would skip Saturday, completely. Locals, etc.
Yes, get there early. Some guests do leave in the afternoon, but we do stay almost until closing (or closing) since TL and BB is only open 10-5 when we are there.
