DH suggested that the kids take turns with the beds. As for me, give me a quiet spot and I will be asleep. I don't know how many nights I fell asleep sitting up watching the b**b tube. I must have watched them build the ship a million times.
Please let your DH know that my DH is also certified and would love to take a dip on the Eastern Cruise. As far as my snorkeling, I have grown up around Lakes. There is nothing I hated worse than having to swim in them.

I bought my snorkeling stuff and hoped that God would give me enough strength to get in the water where I couldn't see my feet. He did.
The Cheeze Wiz story goes as follows: Doogie, Lincoln, Willie, John, Trey and I (and Im sorry if I forgot anyone) took off from shore on the first day at CC. Out we went, needless to say, I was a little scared, but I followed them. We got out to about 20 feet deep and the striped yellow fish were following Doogie and Willie. When Willie and Doogie pulled the cans our of their pockets, the fish were all over them. They would squirt the cheese and then there was a feeding frenzy. ( A little over whelming at first) Willie shot the cheese on Trey's mask and we were lucky enough to get it off before he was attacked. All and all it was a great initiation to snorkeling. After that I was hooked. We got to see lobster, star fish, eels and other interesting things in Mexico.
On the shirts I was thinking Baby Yellow with Navy writing. I will see what my guy suggests. He's a mans man, so he will side with the boys. How about Tie Dye. I bought Referee shirts for my employees two summers ago, the kids loved the tie dye, but most of the adults HATED it. But, you know I can find one my refs in a crowd if they have that shirt on.
Good luck on the packing list. Im anal when it comes to packing. I am with you on bathing suits, cover ups and dress up clothes. Maybe one pair of jeans for the clubs and a couple nice shirts.
