I bought a cute little rolling cart that folds up into the size of a folded umbrella. i had it in my carryon bag. I was so excited to use it the first time when I went to get my OL from bell services. But darn it! they had already delivered my OL to my room before I checked in.
I did use when I took my OL back at the end of my stay. The guys in bell services were fascinated by my cart.
My OL is packed to the gills and weighs probably 25-30 lbs. The cart worked just fine.
