We will be flying out of Frankfurt at 8:30am on a Saturday morning.We will be dropping the car off on Friday and we will need to stay at a hotel near the airport. Any suggestions on a good hotel that will provide transportation ( Free is always best) to the airport?
What time do we need to arrive at the airport?

People generally try to be helpful here. If I gave you a vague answer like "sure, there are plenty of hotels near airports in Europe", it would be about as helful as your question "Airport Hotels". Did you ever think about putting "Frankfurt" in your title?

Are you a priceline person? Have you tried priceline -- they have listings of hotels in the airport area. You could probably get a good price.

I would get to the airport at 6am.

Hi saycheese: There is a very convenient Sheraton hotel inside of the Frankfurt airport, however, it is very pricey, you can check it out online, all you have to do is walk across the skyway and you're in the airport. This year we will stay at an Ibis hotel in kelsterbach which has a shuttle, you can also find info on this hotel online, the price is much, much less than the Sheraton but of course not as convenient.

A couple of years ago, we stayed at a Holiday Inn Express in Moerfelden, just 5-7 minutes from the airport. We paid under 70 Euro by booking online and that included breakfast but I believe there is a 5 Euro charge for their shuttle service.

There is the Sheraton Airport hotel, but this is quite expensive. The Steigenberger Airport is just a few minutes away and they have a free shuttle. But the hotel itself also not the cheapest of them all.
Since you are leaving on Saturday, why not trying the weekend rates of Best Western? There are 2 just a few minutes away from the central train station Frankfurt. And from there the S-Bahn (suburb train) is leaving every 15 minutes or so and just takes about 12 to 14 minutes to the airport.
