I cruised on Costa earlier this year on the Serena and had a great time, so I was really looking forward to cruising with my boyfriend on the Fascinosa. I'll try to keep this brief because we did have a lovely time, just without any help from Costa.
THE GOOD
The ship is brand new. We had a great balcony cabin (8260) with an interactive flat screen TV that had multiple English news channels and one syndicated TLC/Discovery channel. We ended up spending a lot more time in the room than we had anticipated (I'll get to that in a moment), so we were grateful we had the TV. We purchased the all-inclusive drinks package for a VERY reasonable price of $175/week (I believe it was 135 Euro). The package paid for itself. More cruise lines would benefit from this package deal, we didn't meet one person on the ship who didn't purchase the package. The bartenders were fantastic. Our cabin steward was great. No towel animals, but everything was very clean as he stopped by multiple times a day. The waitstaff were friendly. The excursions were alright, but way overpriced (as can begrudgingly be expected). Theoretically, the cruise stops were all fun places to be, had we been able to actually go to them.
Good closet and drawer space, great balcony, quiet room, interactive flatscreen TV with multiple language channels, near stairs, near the central bar lounge, a bit far away from dining room because the layout of the ship requires you to go in an indirect route.
