Nope. Don't need to do that. I've never stood in line for that long to get Palo ressies (brunch or dinner)
You just need to make sure you are at the port EARLY. They now give out numbers and group one boards first (concierge and handicapped) Group 2 boards second (as a big group) etc etc. You'll want to be in one of the early groups. Then you make a BEE-LINE for Rockin Bar D (or is it Wave Bands? can't keep my ships straight) and you go DIRECTLY there. Do not stop to buy a beer mug, do not stop to look at ice sculptures. Go directly there. The lines shouldn't be long if you got to the port early, got an early number, and go directly there.
That being said....don't know who is planning what transportation to get to the port, but.....
DCL transport on their busses is slow. And annoying. I like to have more control over WHEN I get somewhere. Seemed like the one time we took it we stood in line forever. Finally got on a bus and then sat in the bus for what seemed like forever. Then drove to get there and it seemed like we were the slowest vehicle on the road.
We will either drive ourselves there or have a car take us there. That way we have more control of the time. Besides, there will be a big group of DISers congregated in the terminal and the party will start for us before boarding!!!

What? You didn't see the BIG group of people all in grey shirts with the big DIS BOARD MEET sign??? (sorry, inside joke, eh, Mary!?)
