We have just returned from our cruise on the Preziosa. I would like to thank Cruise Critic members who helped me plan the trip with a special thanks to Kat who has written extensively on the forum she shared so much of her trip with everyone. So here is our account of our cruise.
We flew to Marco Polo then caught the Alilaguna Blue line to San Zaccaria, the details of which are to found at "Venice for Visitors" a link from Cruise Critic, they tell you where to buy you tickets (you don't need to decipher the machines in the baggage hall) there is a desk in the arrivals hall, they even have pictures to show you where to go. This was a flat fare of 15€. We decided on this route because of the position of our hotel, "The Bisanzio" there was only one bridge to cross, limiting the number of bridges, a tip given by many Cruise Critic members and probably one of the best pieces of advice I gleaned. We stayed two nights then retuned to San Zaccaria and caught the Alilaguna Blue line again to the cruise terminal 8€.
The Alilaguna docks closer to the terminal building than the People Mover station and no escalator to negotiate.
We had a small balcony cabin which was absolutely fine. The balcony is small but it had two chairs and stool and was ample big enough. The cabin was beautifully furnished and had a lovely bathroom with very clever shower doors that folded in when not in use and made the bathroom seem bigger. My one small negative here is there was nowhere to sit in the cabin, the larger balcony cabins have a sofa. The info given by MSC was the same for all balcony cabins, it is only on the deck plan that you can see that cabin and balcony are smaller.
