All cabins have hair dryers and for wake-up calls use the phone service.
I don't know about single older guys. Best places for meeting them would be the bars/lounges and dance venues.
The cruiseline website has a section for each ship where you should be able to find out exactly what you cabin offers and see a diagram. There used to be a website called cruisestateroom.com where you could take virtual tours of your sateroom. I don't know if it's still around. I haven't visited it for a while. You will have a great cruise and will probably be hooked like DH and I are. We will be in Mexico while you are in the Carib.--a great way to get relief from the yucky winter.
