I would rate Venice among the top five ports to sail in or out of. Spectacular! I personally love Venice, but it is totally handicap-unfriendly as almost all the 400+ bridges are upstairs and downstairs so not easy to navigate with luggage or push strollers. Other reviewers have already described the challenging port, so I shall forbear.
We loved the cruise (very port-intensive); the ports were all interesting; the food was very good; service was excellent; our cabin was spacious and kept spotless by Lavonie.
We loved the ship, lots of natural light from huge windows, BUT....
1. you need to use a credit card (NOT your cabin key-card) for the safe, which defeats the purpose of a safe, IMO.
2. there is no fridge in the cabin, and all the "bar" bottles/drinks were cluttering up the dressing table. (I solved that problem by stashing it all underneath the dressing table).
3. The STENCH! It was mostly in the Centrum, some days bad, other days nauseating, but always there. The captain explained that it depended on the direction of the wind, so I guess the wind was always blowing more or less in the wrong direction! We also smelled it in our corridor sometimes. Fortunately, not in the cabin. This detracted a lot from an otherwise 5-star cruise! I would be very leery of cruising on the Grandeur again because of this problem.
4. Probably correlated to the above, was our toilet which did not flush 3 mornings in a row. Maintenance replied each time that they were working "on the whole area"(?) I spoke to another cruiser whose cabin on deck 8 had problems with the toilet every day, so his "area" was even worse than mine...
I imagine the ship's whole sewage system needs to be revamped.
This was our third cruise with RCI, and I would definitely cruise with them again, but beware of the Grandeur!
