We are off on our 24th visit to Florida in September :-)

You need CDW (Collision Damage waiver) and SLI (Supplemental Liability Insurance) They should include theft insurance as part of the package, along with the various taxes. I use Netflights www.netflights.com and these insurances are included in their package. If there's going to be more than one driver, take the platinum upgrade which will include extra driver cover and a tank of fuel You take the car back empty. They may try to sell you an additional insurance but the bottom line is that it is in case you lock the keys in the car?????

The form that you brother in law is referring to was going to be an issue.

They passed a law, a couple of months back, stating that all foreign drivers needed an International Driving Permit. This even included Canadians. There was such a backlash that they resinded this law within a couple of weeks. Be assured that you do not need that IDP now. You just need both parts of the UK licence with you. i.e. the plastic card and the paper part. I've never been asked for that paper part but some have.

Have a great time and say Hi to Mickey Mouse for me :-)
