DCL is having a hard time pulling us back. We recently canceled our Treasure booking.
We opted to cancel the Treasure booking to go to the London and Paris for a similar spend (including a longer vacation, upscale hotels,
Disneyland Hotel, Paris, for a couple of nights, good theater tickets in London, and a couple of pricey dinners). As much as I love DCL, when I weigh going to the same stale itineraries against seeing parts of Europe we haven't been to, in style, for a similar or less price, the choice is pretty easy.
And when it's time for a tropical vacation, Celebrity is too enticing with a very similar experience, but better food, for much less. We have two Celebrity cruises booked. One of them is an intinary DCL never does anymore (Bermuda from NYC).
We will be back to DCL, but it will either be on a classic ship or when I feel like the price-to-value ratio is better on the newer ones. I love it, but it's hard to peak my interest once I start comparing options for the same vacation spend.
