We will say this - take it or leave it. It is your last day of vacation. Enjoy it. Get up for breakfast at a good time - if you want to be there early, fine, get up earlier BUT - don't sweat it. Don't be a part of that mad rush and if you happen to be in line, there is nothing to stress about.
With the expanded beach there is plenty of room, even with the large ships. If you really need a beachfront spot to watch your kids play, you can always pick up a chair or lounger and move it.
The last three times we went, we have always leisurely got off the ship and there were plenty of great spots available for the taking. Our two cents....
(plus you can take the tram all the way to pelican point and there is always good space there. We have our favorite spot on this peninsula and that has always had space....)
