We need all your help and expereince again please.

I've read some of the otehr posts about US - IOA which in places is relatively positive but in others quite negative. Last year we spent 4 days at disney and a further 3 at the water parks, this year we though just 1 day at disney and maybe buy a 4 park flex ticket ?

My question is how suitable is Universal/IOA for 12, 10, 7 and 4 year old girls, we know that sea world would be fantastic but would we be better to just stick to disney at these ages.

Also could I have some views on the quality and cleanliness of the universal/IOA parks and rides; are all of them open (seemed to be some debate that alot were being refurbished?) and are they good fun ?

Once again, thanks in advance for your help
