Any tips on best LHR places to grab a shower and freshen up, even if in other terminals? I'd also be interested to hear about your suggestions for Hotel day-rooms for those that have 6-9 hours of transit? Any favourite places to eat? Finally, are there any nooks and crannies in the terminal where you can find a quiet corner for a kip?
