YES, DECK 10 FORWARD, MEAN AND PUSHY!
Deck 10 forward-people slept out all night in lounge chairs. Around 4 a.m. the lounge chairs started clearing out, deck 10 forward was STANDING ROOM ONLY, NO CHAIRS. People were there by 5 a.m. and it was PACKED!
Deck 10 midship-more casual, same with deck 9. Just remember, EVERYONE was out for the first locks, then it settled down because it is a slow process going through the locks. Deck 4 is also a great place to be because you can get some shade and also the verandahs. Alot of people headed off to breakfast after we actually got into the locks.
Also,
DCL put up a big white tent cover over the basketball courts on deck 10 so there was shade at the front of the ship, but if you were in front of the forward wind shield glass thingy, there was no shade but it was 5-10 people deep everywhere trying to take pictures. It settled down once we got through the first locks.
After that people were spread out everywhere all day on the ship so then it became easier to get around. Just remember not to "Throw" Disney soaps, shampoos, conditioners, etc., off the ship to the transit workers. People were throwing them off giving them "gifts" and the Captain made an announcement to please not throw things off. I guess the cruise ship can get fined by the PC Transit Authority if guests are "littering" as they go through......not that we threw any gifts off to any of the workers or anything.
