It's great you can afford to cruise Disney that often without using discounts. I've honestly never paid more than 5k for a
DCL cruise. I've been really lucky with the GT and interline rates over the years. It was easy with the old website to watch cruises and see what cruises weren't selling. It was actually kind of fun. With the new awful website forget it. I don't even look anymore.
The San Juan cruise was great. I may do that again next year because those are always discounted, same with Galveston, New York, repositioning cruises and some European cruises. I still have options if I want DCL, but I've gotten over the urge to spend the big bucks to go back on the Fantasy or Dream. After sailing on the Vista I've decided I can get my mega ship fix with Carnival.
I think the best way to overcome the boredom is to visit new ports. Spreading your wings out of Florida will help with that. San Juan, Alaska, TA all sound good. I was even excited for our Galveston cruise just because I'd never been to Galveston. Changing things up definitely helps.
