We are doing the Venice to Barcelona in June on Millie. We were on the Mille once before in the Caribbean. We had a CC on on deck 9. We did not have a problem with noise but there is a big overhang over the decks so this cruise we went one deck lower in a CC. We have had a sky suite on Century with butler. They will do whatever you need in reason. We did not require anything special but it was nice to be pampered.
On this trip coming up we did not use Celebrity excursions. We booked private drivers for Rome,Naples, Florence, and Athens. We wanted to be able to set our own itinerary.
