Just had a lovely cruise on Wonder of the Seas. Just wanted to share what electrical options were in our stateroom (balcony room on deck 10).
So, under the main mirror opposite the sofa-bed:
2 EU-type power sockets
3 US-type power sockets
2 USB sockets
Then on each side of the double bed, a lamp with extra power sockets:
1 USB Socket
1 US-type socket - seen here powering my excellent Lowenstein sleep-apnea CPAP machine which fitted nicely on the bedside table like it was made for it!
If you're interested, we fast-charged our USB devices using this excellent Lencent pass-thru plug charger:
