Some of us like the product and will sail it again when the value is right. My quick ex. Is 2016, 9 night back to back was cheaper than a six night back to back in 2017, both on the Magic out of Miami with the same islands except for one that the 6 night didn’t go to. For us it was a slam dunk, we weren’t paying more for 3 days less vacation. If DCL is similar in price to other lines we would consider it again and would like to sail the new ships. We however are thrifty cruisers by choice which is why we look at price so closely.I always find these posts fun to read. Especially the people who will come to a Disney cruise line specific forum and claim that they have left DCL with no intention of ever returning. (then why are you on these forums? I know that may sound offensive but it is an honest question not a barb)
From what I have read over the years, it is like anything else, a personal decision which should be made by comparing the specific cruises against your personal list of criteria.
Some people will choose busch gardens or seaworld over disney world every day of the week because of cheaper ticket prices. Others will compare restaurants, quality of food, attractions, park hours, parking, number and size of bathrooms, whether they offer plastic or paper straws, etc. and proudly proclaim that their choice is "better." And, for them, it probably is. But, bashing seaworld because they don't have enough rides for a family that is looking for roller coasters makes as much sense as bashing busch gardens because they don'e have enough sharks. Everything comes down to want you are looking for and it should be a total package evaluation not just picking a couple variables that "match up" and claiming it makes the comparison apples to apples.
If you like a particular cruise line and do not want to try a different one, that is entirely up to you. If you have had a particularly bad, or good, experience on a trip and want to share, then I would say that is what these boards are for. (the sharing of knowledge)
In the meantime, I'll sit back and watch while people get vicious defending there chosen territory and attacking the ones they dislike.
