The Category 11 rooms (suites) on the Pride are similar to the penthouse (category 12) suites. The only major difference is in the square footage of the room and balcony. The category 11 suites are slightly smaller inside and have a slightly smaller balcony. Here is a website that lists what each room category has on the Pride: http://www.choosingcruising.co.uk/cruiseweb/cabins.asp?client=choosing&nShip=271
Camp Carnival activities may vary slightly by ship, however you can go to the Carnival website and on the top line menu there is a selection called Onboard Fun. Under that category select Youth Programs. Camp Carnival is located under that heading. There is some generic information listed there for toddlers (2 - 5 yrs), juniors (6 - 8 yrs), and intermediates (9 - 11 yrs) There is also a video clip (about 5 minutes long), from the Carnival Freedom, which gives you an idea of what Camp Carnival has to offer.
Hope this helps....have a safe flight from the UK to the US and have a great time on your cruise!!
