We had a hirdryer in the suite - it was in the closet. I too had limp hair and used my own shampoo.
There is still a very pronounced vibration on this ship. I've done 12 cruises and this ship has the most vibration I've ever experienced. There are tables in the Compass Rose in the middle rear that you really want to avoid. I also found that Portofino had a constant vibration when sailing that was annoying to me - I ate lunch in the dining room several times to avoid this. We had dinner there on an overnight evening so as to avoid the vibration.
I will also say AVOID any odd numbered (starboard) cabins on deck 5. There is a "motor/pump" noise that comes on and off 24/7 and I lost sleep every night because of it. I was not the only one who heard this noise - others in cabins nearby were complaining too. I was very disappointed that when I asked about the noise no one seemed to know what I was talking about - I know this has to have been an problem before and their not at least acknowledging it was an issue with me. I made comments on the questionaire about it but doubt I will get any response as I couldn't get one on the ship.
I agree the cabin set-up are more than we'd drink in a week as we like to socialize before dinner in the bars.
