When you say "surge protector", I am assuming you mean an electrical outlet. Bring one as there is usually only one plug in a room and with all the gadgets we bring, you'll need more outlets.
Bring a case of water in a duffle bag. Just check the whole thing in and use the bag as a dirty clothes hamper when you're done. At $3.50 a pop for a bottle of water, you will thank me for this one.
Have a fantastic time!
