Good to know, I think I'll try that next time. As some-one said, it's more efficent.

Then again, If they frown upon couples showering together, can you imagine how big the frown will be when me and my husband go in together. I'll get the boot for sure! I went into the Calgary MLL with my partner, holding hands once and the looks I got was enough to turn anyone into Stone.

Back on topic,
I know the Arrivals lounge in LHR for sure has showers. Never used them, but they looked nice.
