Hi and welcome to TUG!
There is a lot of great info. and pictures about this resort in the old posts. To find them, click on the "search this forum" button, and search for the word Lagunamar.
Curious - what did you wish that you had taken to Hawaii, that you couldn't buy there? We are of the "less is more" mindset and go to Hawaii for 2 weeks every summer with just one carry-on bag each.
Have a great trip!
