We were on the Sun this year and last year, simply because it sailed from Canaveral and the other options didn't thrill us, i.e., RCCL, Carnival and Disney.
When we stepped off we knew we would never sail with them again. The food was not good. We ate in specialty restaurants every night because of it. When we did go in the dining room I could not get used to a "bare" table. Not a flower in sight. The tables (at night) looked like they had been set for dinner and forgotten. This is a very big deal to me.
On the other hand, their shows are excellent.
Now that the Sun is finding herself in Miami, there is no chance of ever sailing that line again. If we go to Miami, it will be Oceania; if we go to FLL, it will be HAL.
