Cruising is great fun - you don’t even feel like you’re in the middle of the ocean half of the time.
That being said, you might want to start out with a shorter cruise so that your wife can get the feel of it if she still isn’t too confident about being in the middle of the ocean.
Where are you thinking about going? Do you definitely want to do Disney?
Most Caribbean cruises are 7 nights in length, and the shorter cruises range from 3-5 nights. The longer cruises departing from the US are typically transatlantic or holiday specials. We can usually find 8 and 9-night Caribbean cruises over Christmas (not Disney), but it’s a little more difficult during the summer. We’re considering some 10-night roundtrip Panama Canal cruises on Princess in December.
Over the summer, most cruiselines move to Europe. Disney has longer itineraries in Europe during the summer, but they are on the Wonder (I think - one of the smaller ships). If you want to cruise on the Dream or the Fantasy, right now you’re limited to the Caribbean. There is an 8-night cruise departing from NYC to the Bahamas this summer… but I think it’s almost sold out.
Another option is a back-to-back cruise. This is when you stay on the cruise ship for the next sailing when other passengers are disembarking. You can also get off the ship at Port Canaveral if you’d like. Of course, it’s best with the 7-night western/7-night eastern itineraries. I don’t think it would be very interesting to do a 3-night Bahama/5-night Bahama cruise…
Congrats on the opened option of cruising!!! They are ADDICTING, just like Disney!
