I am going to be flying through London Heathrow Airport on my way to Johannesburg next month and I will have an 11 hour layover. I was wondering if anyone could tell me about Heathrow:
1) Is the airport itself hard to get around in and confusing?
2) Are there places to take showers (and are they fairly clean) and to sleep, like larger chairs or recliners?
3) What about duty free shopping?
4) Is 11 hours enough time to do any sightseeing or should I just hang around the airport?
ANY help would be greatly appreciated!!
