You lucked out, Saturday was a buy out day for Pfizer which got cancelled.
Now you just need to worry about the rain. If the rain does hold out , you can catch the brand new Fireworks show !
With the rain , I'd play Sunday by ear with the flash pass. It wouldn't hurt getting one since you only have a day to do the park. Unless it's ultra packed, I would than get a Gold.
I always do Sfgadv counter clockwise. Start with the Dark Knight, B:tr, Nitro, Skull Mt, Blackbltt, Bizarro, El Toro, Rolling Thunder, Ka, Gasm, Supes. You also have Saturday night to figure out which way would for you as well.
Supes, Ka, Toro, Bizarro and Nitro will have decent size lines anywhere from an 45 minutes to an hour. This was yesterday and most schools aren't out yet. Rolling Thunder is the slowest line in the park, Try and ride Saturday in the rain. Should make for a better ride anyway.
Best of the West hands down is great inside the park. They also do have a new eatery complex on the boardwalk. I haven't been so I couldn't tell you, sorry. Plus run of the mill things like Nathan's, Johnny Rockets and Papa John's
Outside you can find pizza, mexican, wawa, Kfc , Dunkin, Mc Donalds, and Burger King all within a mile of the park.
Going around the city seems fine , NJTP is either 14-15 dollars for the whole thing. I know from exit 3 to 7a is $1.60 and to go to exit 14a is only 5.50 from exit 3 . It's not that bad compared to Pa. Look to spend $6 from Nyc to 7a. Might even google that to check.
295 and 195 are pretty much normal roads with pretty much light traffic. Nothing like the loop in DC.
