I never really pay attention to that type of thing because I don't travel with anything that needs a special outlet. There was a microwave and fridge in my room so there may be a 220 in that area.
Not something I paid alot of attention to on my stay there if you are needing a heavy duty plug but the ones in your room are all standard house plugs (110). It is a hotel so parts have been wired for both. Housekeeping or maintenance have access to a 220.
