I'm sorry to hear that. We almost did a switch to an alternative line for our med cruise, but ended up sticking with
DCL. We sailed a week ago and I really enjoyed the cruise and thought about how glad I was we stuck with DCL multiple times during it. However, my wife and I are about to book Princess for Alaska next summer. Now I am second guessing our decision.
What areas of service were lacking? How was the general ambiance of the ships? The service, classic ship designs, lack of smoking, enjoyable meals, and general "feel" of DCL is what we really connect with. The shows are nice, but not critical for us. The characters aren't at all important to us, although I enjoy seeing little ones get excited for them. Evening entertainment is fun but not critical to us either. And my wife isn't a sit-by-the-pool type of person, so I only do it occasionally. So it really mostly just the general vibe of the ship and service.
Added: I think I also generally like the people that sail DCL. It seems we have a lot of similar interests and they are generally nice folks. Our Med cruise Facebook group rocked.
