First Carnival cruise - Jubilee - about 15 years ago. This was a Panama Canal (part way in) to near the Equator...NO AIR CONDITIONING!!! No, it didn't break down on our cruise; it actually broke on the cruise before ours. Of course, they didn't bother to tell any of the passengers who were boarding for the next trip...nor did they try to fix the A/C. Heaven help you if you were a diabetic...the only sugar reduced dessert was yellow cake. Every night they did change the frosting to another color and they gave it a different name (i.e., pink was strawberry; yellow was lemon; green was mint, etc., etc.). Okay, this was an old ship even at that time but it was always very dirty (perhaps, it was also too uncomfortable for the crew to keep things shipshape (no pun intended). After this cruise, my husband and I swore we would never sail with Carnival again. So much for swearing...move forward about 15 years...
Our second (and, without a doubt our very last, forever, no way) cruise was on the Splendor. It was a brand new ship with only two voyages before ours. It was cruising out of Dover, England and would be visiting Northern Europe/Baltic ports. Our brother and sister-in-law talked us into joining them on this trip. Although we were very hesitant to go on this cruise, we decided we would give Carnival another try. I mean a brand new ship - how bad could itt be? Pretty bad, if you want my opinion.
. We were on the Spa deck (10) in a handicap room (at the very front of the ship - there are two locations on board the ship for handicap access rooms (the very front or the very back (right next to the crew's metal stairway!). The doorways to these cabins have a wall opposite them making maneuverability difficult if you're using a motorized scooter. They door to the room does open automatically to let you get in when you put your card in the slot (we didn't know about this feature until we were five days into the trip because the door was not functioning when we got on the ship). One problem with that was that the door automatically closed whether you were in the room or in the doorway...smash!!!!!!!!!!! goes the door into your scooter, leg, etc.
. Food was alright (nothing special). The desserts (sugar-free) were the same as on our first cruise... The food court was very disorganized and at some points on the line you actually had to reach across food to get to other food (yuck!).
. The Styrofoam carvings were - well - there! Ugly - if they didn't want to do fruit carvings or ice carvings... okay, but Styrofoam with plastic flowers just didn't meet our standards.
. Shore excursions - who knows! If you were unable to walk well or couldn't climb steps - you needn't bother to book any tours. You can get off the ship and ride your scooter or wheelchair up and down the dock - but, don't expect to go sightseeing.
I could go on and on, but I won't. I would like to add one bit of information though, 10 years prior to this cruise we went on the Royal Princess to the same ports (with the exception of Germany) and it was FABULOUS!!!
