OK, so I know there's no Walmart in Frankfurt...

We'll be flying into Frankfurt in the late afternoon, and would like to find a large Walmart-type or even "Babies R Us"-type of store identified and plugged into the GPS for a quick stop before hitting the hotel and crashing after a long flight.

We're going to be in the market for a portable baby sleeping unit. Something cheap and disposable after a 3-week trip. Something like a bassinet, playard, playpen, etc. that folds down and up easily and doesn't take up much space in small European hotel rooms.

Does anybody know of a store that would carry something like this (cheaply) in Frankfurt - bonus points if it's near the airport, and double bonus points if it has a web site where we could look online and get a good idea of what we'd be able to find there before we fly...

Thanks in advance for your help and suggestions.
