Hi! My boyfriend and I are sailing 6/6 on the Ruby Princess in a caribe deck balcony and I have a question about under the bed storage. I have looked up, and there was an actual Youtube video, of our cabin which was very, very nice. I sleep on the left side of the bed with my c-pap. I saw there is a plug on the right side nightstand and was wondering if I can run my 4ft extension cord (cruise approved, non surge protected) under the bed? Is it hollow under the bed or did they put the mattress on a block nullifying the under bed? Also, if it is hollow can you store your unpacked suitcases also? Trying to maximize space! Thank you in advance.
