My family of 4 just got back from the Carnival Splendor April 26, 2009 and this is how it went:
We were in cabin #2409 regular outside. Our party was my husband 49, I 43 and boy 5 and girl 3. Everyone is platinum except the girl and adults have 25 cruises with Carnival. I do have to say that for several reasons this was our worst cruise ever.
We got to the port of Long Beach just at 2 PM on the 26th to board. They have done a bit of construction at the pier and now they have a little building on the left for platinum and V.I.P. types. In the back of the building on the left are some restrooms. I think they are new but look old. I did not go in. You can get to these restrooms from the outside as well.
Low hall noise. Good location for laundry and elevators midship and aft. Good water pressure in shower. Would stay in this cabin again.
