I want to tell you to bring chocolate dipped strawberries. I realize this is not the most convenient in a hotel room. 
But it’s sort of that balance of healthy and not and people get excited to see/have them! You could technically wash and dry fruit in your room and if you have a microwave use the cardboard containers of chocolate disks you find in the produce section for dipping fruit. Bring a little parchment paper and a pretty plate…
I know too complicated but it sounds really good!!
