I agree with Barry about the continental breakfast - that is the best way to go!
With regard to FOTL, they did scan our room keys at some of the rides, but not always. On Friday at IOA, they scanned our keys at The Hulk, Spiderman, Dr. Doom, The Cat in the Hat. It was really hit or miss. Our keys were not scanned at Jurassic Park or Dueling Dragons. Same situation at Universal Studios on Saturday. Sometimes they scanned the keys and other times not. It was not a problem at all. We just couldn't go right back on a ride if they scanned the key. However, the lines in the morning weren't very long and if we wanted to ride again, we could just stand in the regular line. We didn't do that, however.
We stayed in a Deluxe Pool View Room with two queen beds. It was a lovely room with a very nice bathroom. The room was large - with a terrace overlooking the Villa Pool (dead center).
We paid $180 (Entertainment rate).
We did not go in the Beach Pool, so I can't really comment on the slide, but it was a large pool and looked like fun. Both pools were very nice, but we preferred the quiet of the Villa Pool.
We did not eat at Mama Della's. It looked nice, but we just didn't get a chance to eat there - maybe next time. I can recommend the pizza at Sal's Deli/Market. We got in late the first night (after 10:00 p.m.) and Sal's was the only restaurant open at that time. We ordered pizzas and they were excellent.
