we were in 8534 (one of the bigger cat 3 rooms) and it was GORGEOUS and well worth the extra money....
the pull down bed is in the living room...so the kids would all be in the living room (and there are two FULL baths in the cat 3 making it much much much more convenient than the cat 4 family suites...the kids would have a bathroom with a shower in it....your bathroom would have a bath and shower)....
and tehre's tons of stirage space as well..
they are slightly cramped at night when the beds are opened, but the CMs make the rooms up again first thing in the morning, so there's lots of room druing the day...
plus it's nice to have 2 tvs when you're traveling with kids...
since you know in advance which room you're getting, you'll know if you have one of these 4 staterooms (8032,8034, 8532, 8534)....at least we knew which room we were getting (we booked directly with
DCL).....i looked at the deckplan when i made the reservation and immediately saw that 8534 was much bigger than most of the other cat 3 rooms...that's why i took it...
as i said, it was well worth the extra money i paid over the cat 4 (and for us it was $2000 more, since i booked so far in advance i had a huge discount for the cat 4 room i'd reserved, but the cat 3 rooms weren't discounted....so the extra cost was quite significant....it was worth every penny i paid)...
bottom line....if i were you i'd go with one of those 4 large cat 3 rooms......it's a special occasion....those rooms will make you FEEL as if it's special....they are beautiful....
