About double shifts and overtime...
If you're an MI and salaried you won't get the luxury of being paid more for these things.
As for Coral Cay, just make sure your landlord isn't going into foreclosure. I didn't live there, but lived about a minute or two away at Club Cortile vacation homes. I think vacation homes are a great option, really easy to live in without worrying about packing your whole life with you. You can go online to see if the property you're moving into is at least up to date on it's property taxes.
I got a puppy after my last PI though, so if I'm lucky enough to get another one in the spring I have to look for another option.
