Beautiful ship, lovely crew children permitted to take over the pools and night clubs !! by strobino

Traveled with Costa before and we were VERY pleased. It was very frustrating that so many children controlled the pools without being corrected and they were permitted in the clubs until the wee hours.

There are kids in every corner of the ship, including the adult only areas. The Italian staff LOVE to use the overhead speakers. There is an announcement every 15 minutes (very annoying)
