I didnt notice a "cruise ship", unless you are referring to the"sail barge" from "Return of the Jedi" , sitting right next to the Sarlac Pit from same movie, & the "Galaxy Quest" rock monster.
I've also noticed that sometimes the TOS Enterprise, will be flying in the far background, then it will be in the foreground.
The more I watch, the more things I pickup. For example, the some things are grouped in a category. For example "desert planet theme" - "Dune" Spice Harvester & Sandworm, with "Jedi" Sail Barge & Sarlac Pit, and the GQ Rock Monster. The 'Star Wars" theme has the light sabers, window from the Falcon, and the light panels from the Death Star, (Look above & below the cat)just to mention a few items.
Thanks to everyone for your help with the easter eggs.
