1st - Welcome to TPR
2nd - While no one can predict the crowds, we can speak from experience. It'll be decently crowded due to some schools being out for Spring Break already. I would invest in a Flash Pass if you're pressed for time and/or have little patience. If you aren't pressed for time and/or don't want to invest in a Flash Pass then my advice would be to arrive at the park at approximately 9:30am so that you can be at the gate when they open.
My route whenever I go to the park is as follows: X2, Tatsu, Deja Vu, Termipocalypse, Riddler's, Batman, Goliath, Scream. Add in S:EFK between X2 and Tatsu or between Tatsu and Deja Vu. Once I've done that I add in Ninja, Goldrusher, Viper, any water attractions etc.....Yes, I'm aware that my method will require a little back tracking but the 1st 4 attractions I mentioned will have the longest lines especially if Tatsu is still running 1 train. (It shouldn't, but plan like it will be)
Hope this helps. We will expect to see some pictures when you return from your visit
