Hi! Happy to try to add some helpful info!
No - I didn't ask. I suppose if you asked concierge they would assist. But i did ask concierge how to get to myself and luggage to the cruise level and there was no suggestion of the hotel to assist. The person i spoke to didn't even seem to understand the process. I was expecting this to be more seamless.
Don't worry too much about customs... they will get you through. I think we showed our paperwork 3 or 4 times. Do yourself a favor and make sure the line you are in is the correct line. Don't be afraid to ask questions. I saw more than 1 set of travelers in the wrong ship queue. This is why i said the process was a bit confusing and could have used more
DCL employees. Don't worry though, we arrived at 11am and it took 30 mins total.
