I have been lurking here for some time gathering information for our first cruise on the Norwegian Sky 11/22 - 11/29. Everybody here is so knowledgable. I only have a few questions. What time can we board the ship? Also, we are flying in a day early. Can we check our luggage in at the dock and then go back into San Juan for more sight-seeing before we finally board? Can you take towels from the ship on the islands with you? Thank you.
