I have a resort map which will answer a lot of your questions about cottage placement. I can't seem to upload it to here so please email me so I can send it to you that way. Also have directions to the checkin center (as of 2006) which I will also scan and send.
Staying in 31, you will have close proximity to the locked pedestrian gate which leads out of Port O"Call's grounds into the streets; from there it is a few blocks to the beach. This beach will not have lifeguards.
When you see the map you will see parking next to the Crowne Plaza resort, this is another way to get to the beach, by car, and will be a beach with lifeguards. Parking runs for several blocks away from the beach and does fill up early.
The cottages except for the one we were in (39) all have screened in porches. There are two bedrooms on the ground floor and another upstairs, each with their own bathroom.
