Thanks Cruiseej for the information with pics above. I just bought a version of this on Amazon for about $12. We just returned from the Quest and the outlets/ports are located in 4 places: 2 USB ports on one side of the bed. One US plug in the wet bar itself, and one on the floor between the TV and the table. There is a Euro outlet in the "makeup" area (sitting area with mirror) just outside the bathroom. There also may be a Euro plug next the the US one in the bar area. My wife has 3 devices to charge and I have one...this device will work perfectly for her so she does not have to spread her stuff around the room. Also note, if you have a Euro adapter plug that allows you plug in your US plugs for PC, phones, tablets and the like then you can also use the existing Euro sockets for these. Do not use them for things like hair dryers however.
