Its disappointing when you feel like that about somewhere - especially when you were looking forward to it and paid so much to get in there in the first place! On one of our visits we were given a ticket and a time to come back so we could get into WWoHP - that was a bit of a surprise!!
I know the grooves in the floor that you mean at jurassic park, up until you mentioned it id never even considered them to be a bit of a pain (literally in some cases im sure!) but now i can see where your coming from. Not really very good you had to go moving poles and things so you could get in either
