I've loved reading your journal! You've worked so hard! It sounds like you're going to have a fabulous time! And your dress is a big "wow"!
If you opt to go on another 3- or 4-night cruise, and you like Atlantis, definitely book a room at the Comfort Suites. You can get all the amenities of Atlantis for about $180 per four people!
We took a 4-night in January, and we walked around Atlantis (we took a cab to the ferry port for a dolphin encounter, and Atlantis is across the street), and we decided we definitely wanted to do Aquaventure. We found out that you can book a room overnight and then get to go to Aquaventure. We're going on one next January again and doing the Comfort Suites. Definitely a deal! I've talked to several people who have done it, and it's great.
I can't wait to see pictures!
