Hi skipz
We have put the luggage in the car before now and gone off for the day before our late flight and its been fine, although we can get it all out of sight in the boot which helps.
You can park at the airport just follow the signs, it is fairly secure and you can get a taxi across the road to Mahon for approx 10€. As for things to do, you have the shops for last minute presents or take a walk around the harbour and have a cheeky gin from the Xoriguer factory
I don't know what time of the year you are visiting, but you maybe lucky and be able to keep your villa on if they do not have a let straight after you, just e-mail the company and ask them.
Alan
