If Icon is bad, Oasis is 3 times worse than on sea days on the pool deck. I've experienced it on Oasis. It's not fun. The whole Oasis class is so spacious is a myth on sea days. Also, no more whole one side of the pool deck is a smokefest. No more of that on Icon. One section far away from the pool is the smoking ara, no longer the whole pool deck on one side. Never had a problem during my Icon cruise with loungers. They 5,610 people onboard the Icon.... Also the promenade and Central park blow away Oasis class, so much wider and more room, no congestion. Central Park was so tight in the pathways on Oasis class, not anymore on Icon.
Basically if you ever sailed Oasis class full capacity and enjoyed, you won't have a problem here in my opinion. There are so many more loungers to choose from, Promenade way more spacious without those islands in the middle to sell crap and the central park pathways are wide, no more getting stuck behind slow pokes or someone constantly stopping to take a photo.. Lines for waterslides? Oasis class has 3 slides, Icon has 6.
I wouldnt pay these prices either, I got a balcony room in Oct of 22 for 3 people for 4,100 dollars.
It will be 3-4 years before the demand for Icon class wanes, these ships are Oasis perfected.
