We have done close to 40 cruises through the years and wanted to try a ship we had not been on before, as it went to the same places we had been to numerous times.
For us it became an experience that needs to be passed on to older experienced cruisers
Before the cruise, be sure you book as many of the shows and specialty dining rooms ONLINE. We were not made aware of this by our travel agent, So if you wait to do so onboard you may not get what you want probably because there are so many Comp Specialty Dining packages being offered, you may not get many of the places you would like . Most of the shows must be registered for as well as the Specialty Dining (which we new from past experience). If you are elderly you will find some of them too noisy more than likely.
