Just got back from Pop on Sunday. We had an incredible time. The fridge really came in handy. Note to future swappers. I taped the coffee maker box and the toaster box to the top of the fridge box. My daughter stuck a big "Nemo" fish decal on the box to make it more identifiable for the people at luggage service. The box has a "false bottom" being held in place by 2 plastic straps. Do not discard the straps. Just remove the straps and lift the box upward. The fridge was easier to access this way.
Defrosting the fridge only took several hours. I just turned the unit off, left the door open and placed a towel underneath the freezer section to collect the melted frost.
The CMs at luggage service were very helpful. The line to store luggage was long and I went straight to the counter and asked if I could just drop off the fridge for the next guest. The CM gave me a claim ticket and took it right away.
The fridge is light but bulky so ask for a luggage cart.
Many thanks to Scramez for doing a great job.
