For those on the first leg of the WC, or anyone returning from South Africa to the States with a long trip/flight like we have(31 hrs 46 min) thru Frankfurt, I think I've found the best way to break the trip. The Sheraton Frankfurt Hotel and Towers is right in the airport at Rhein Main. You don't even have to go outside. And, they will let you checkin early in most cases. Prices are reasonable for Europe and breakfast is included. It's a lot better than paying for business class to do the trip in one shot. Check it out on tripadvisor or the Sheraton website. Looks like a really nice place and it gets great reviews.
