Dsny06,
We were worried about the tendering process as well. We went down to the Buena Vista Theater around 7:10am (if my timing is right). The first tender was listed at 7:30am. We were the first to arrive. We showed them our e-mail confirmation to let them know we had to get there for a tour. He asked why we didn't book with Disney if we were so worried about getting there in time. I told him we would have if they offered the tour (however, probably not!) Long story short, he got us on the first tender which was still wide open when we left the ship. Right thru the gate was a man holding a NATIVE WAY sign. He asked us to wait across the street near the ROLEX sign. We ended up waiting about 45-60 mins for others to arrive.
You'll love the tour! Guides are fun and really get you into the action. I would suggest sitting up top. They let our 7 yr old DD drive the boat for quite awhile. Be sure to bring an underwater camera - also, they do have a guy videotaping everything. You can buy for about $60. Yes, we did get one as well.
First we went to swim with the stingrays. So neat! One of the highlights of our trip. Next was snorkling. Not my favorite but lots of people loved it. I ending up hitting some shark (don't know what kind - harmless I guess) in the nose with my flipper. I was freaked out and he wouldn't stop following me. I almost drowned my husband in the process. He thought it was hilarious! Not me.
Next was Rum Point. Beautiful beach but pretty crowded. No beach chairs left but plenty of picnic tables. We were there for about 1 1/2 hours. Kids spent all of their time in the water. We were given menus on the boat right away to place our orders. Decent size menu - hamburgers, hotdogs, salads, tuna, chicken - food was good and waiting for us when we arrived - nice touch. Beer was EXPENSIVE! You might be able to put in a specific request. Seems like that would be possible. If not on the boat, just wait until you get there to order.
Have a great time! Kiss a stingray for us!
