For a first cruise choosing between a veranda or just an ocean view I would take the veranda. It does add so much more to your cruise without knowing it.
Choosing between a double dip to
Castaway Cay or not, that is a tough one. How much do you like the beach is going to be the deciding point. Your first time to Castaway Cay will be fantastic! With a double dip, if one day you are unable to dock (which does happen, but VERY rarely!) at least you will have another day to try.
Is the Fantasy old and dated?
Well technically it is 12 years old so I guess it is old.
Is it dated?
The Wish and Fantasy are 2 completely different designs of ships. The Wish has more of a WOW factor with the Fantasy having a much more classic cruise ship feel. Yes the Wish is beautiful as it should be since it is new.
But is the Fantasy dated? That is really in the eyes of the beholder. Compared to the Wish? Well maybe but like I said they are 2 different designs.
If your 7 year old is going to the kids club, the Wish might have a slight advantage. We do not have kids that age but we took a tour of it and it looked fantastic! I can't say anything about the Fantasy since we have never toured the kids club on it.
As for the food being better on the Wish, we saw a definite decline in quality when the ships started sailing again after the shutdown but believe it has come back. I think it took the chefs a little time to get back in sink plus the fact of probably having a lot of new chefs took a toll on the food. But we may not be as finicky about the food as others.
We have done 21 cruises strictly on Disney (with 22 & 23 B2B coming very shortly on the Magic and 24 in June on the Wish) and yes we have seen many things we liked about the Wish. But we have also seen far to many things we have not liked. All of us that don't really like the Wish really wanted to love it when it came out but we see things past the glitz and glamor that do not bode well with us (and it is not nostalgia for the old ships).
Do we hate the Wish? No but we DEFINITELY do not like it.
But for you and a first time cruise, only you can decide if you want to sail on a classic ship with more time at the beach or do you want to go with the WOW factor of glitz and glamor of the new ship and have a veranda stateroom?
As much as I really hate to say it, I think the Wish with a veranda for your first cruise would be a great choice.
But you cannot go wrong with the Fantasy! And if you would chose the Fantasy, I would definitely recommend trying to come up with the extra for a veranda.
