Chose this cruise because of the Estonian connection and also wanted to get a feel for a much larger ship than the ones we have been on before. The embarkation was terrible because of computer malfunction and to get over 6000 people on board was slow, 3hour stand in line, process. Must have a back-up system to prevent something like this! Once on board, the friendly staff improved my attitude. To get to our cabin, mid-ship, was quite a long walk and I would recommend for older people without wheelchairs to request a cabin closer to the elevators. The cabin was satisfactory as was the balcony. We were traveling with adult children and their spouses, so were able to dine together as a group of 8. Had the same table most nights and great waiters. Food was satisfactory and ample. No need to go to specialty venues and pay extra.
Nightly entertainment was super! The aqua show was unique and the Blue Planet show also amazing. There was a group of about 450 Estonians on this cruise and special concerts and lectures were with guest performers. Thus we had a busy schedule and did not have time to partake in the many activities offered by the ship. And there were many and varied activities for all ages! The younger kids were constantly busy. Some older "kids" even ventured to try rock-climbing.
The port days were OK but not particularly memorable. We toured on our own except took a catamaran in Cozumel.
