Horizon outlets and gift ideas

[mominwestlake]

My son is sailing on the Horizon and I'd like to gift him a Christmas gift of things he will need on his cruise.
How many outlets are in the cabin and where are they located?  Any ideas for necessary items

that would make a good Christmas gift?  He's 26 and will be going with his girlfriend so the gift will be for both of them.

He has cruised before, she has not.

Best would probably be a cruise line gift card.  We buy those periodically then load them when cruising then generally use them for guilt free excursions.  Or specialty dinner.
