It is beyond worth it. You will LOVE it. Yes, you can ride over and over again. ( We rode Jimmy Neutron literally 25 times in a row.......... we didn't even get off the ride) the guy said, just stay, no point in going out, then right back in............ we were in the stationary seats though, my ds was 3 at the time, and refused the regular seats after one ride............... UHHH anyway, depending on when your trip is, you should not have more than a 10 min. wait for anything................ and sometimes you just walk on!!!
You will also LOVE the RPR, it is our favorite resort!!!! We were treated like royalty there!! ( ask for tower 1, highest level you can get, and ask for a view of hulk) they WILL try to give it to you, and you'll have an awesome view of the park from your room!!!
Have a good time!!!
