I've been reading up on Frankfurt lounges for 20 minutes and am totally confused.

I'm arriving in Frankfurt tomorrow morning from Mumbai on Lufthansa. I have a 3-4 hour layover, then I fly to EWR on CO. I've done the 'take the train into the city' thing before and don't want to bother on this trip.

I'm flying coach but am CO Plat/*G.

Which lounges can I get into, and which one SHOULD I get into? I'd like a shower, a snack, and power/internet access, preferably at a workstation.

Thanks,

Truly
