I'm late to the party, and these questions have been addressed by a lot of people already, but there are my responses:
So excited about booking a cruise in 2020 but honestly I know nothing about cruises. Before I book I'm hoping that I can get a few answers first. It will be my husband and I, and a possibility my 17 year old (at the time) son.
1. Where is the best place to request a room on the ship? We don't know if we'll get sea sick, we're not light sleepers, hall noise won't bother us during the day, we like to eat and be social.
First of all, what type of room will you be booking? An inside stateroom? A room with a porthole? A room with a balcony?
We do not stay very much in our stateroom. So anything fancy, such as a porthole or a balcony are wasted on us, since we'd rather be out of our stateroom. So we tend to go for an inside stateroom. On the Dream and Fantasy, the inside staterooms have virtual portholes, which were a hoot! And when you choose an inside stateroom, it really doesn't matter on what level you're at. We discovered when we were cruising on The Fantasy, that having an inside stateroom on Deck 2 was unexpectedly the BEST location for us. There are fewer staterooms on that level, the laundry facility was a lot more convenient and less busy, and, being lower on the ship meant that the rocking motion of the ship during turbulent waters affected us less than those on higher decks. AND, all of the restaurants are either on the same deck or just one deck up. AND, the exit points to get to shore are either one deck up or one deck down, without having to wait for elevators.
We have been requesting inside staterooms on Deck 2 ever since that cruise (they kept "upgrading" us to higher decks in the end).
2. Is there a superior ship between the Wonder, Magic, Dream?
My personal preference is that bigger is better. There are so much more space and breathing room on The Dream and The Fantasy. The adult areas are also much more well-defined and offer a lot more choices, both on Deck 11 and in the "clubs" area. So if I have to choose, I will choose the two bigger ship.
3. What restaurants are a must?
You always get the 3 restaurants on your rotation (unless your cruise is too short to experience all 3). So there is not a "must" there. However, if you're willing to pay extra, I definitely recommend Palo. Have the lamb chops, and order two deserts, with one of them the chocolate souffle.
If your cruise is long enough that you get two visits to Animator's Palette, do not miss the 2nd one, because this is often where you get to draw your own character and get to see them being animated on the screen. It is a lot of fun. So don't miss out on this, or plan your Palo dinner during this time, or decide to skip dining there on that night.
4. Can my 17 year old son sneak onto the adult only beach at Castaway Cay? It sound so much better to us than the family beach.
I do not recommend it. But the family beach, actually, beaches, aren't that bad, because it is rather large, and you don't have to be stuck in the middle of the where the most crowded areas are. Plenty of spaces on the edges and on the fringe, if you're willing to look for it. There are also more food places/spaces there, where on Serenity, you only have one place to get your lunch.
