My parents are flying into T4 (BA) and want to meet up with my aunt and uncle who will be arriving at T3 (United) before they all take the tube into London. It's my aunt's and uncle's first time to London and they don't want to attempt the tube into London on their own (even though I assured them it was easy.)
I haven't ever arrived in T3 so I'm not familiar with where the Underground station is (and the terminal maps on baa.com were not helpful - didn't show where the tube entrance was.) If we tell my aunt and uncle to meet my parents at the entrance to the tube station in T3, is it going to be an easy enough place for them to meet? There aren't like two entrances or anything like that, are there?
Or is there a better place for them to meet up in T3? My parents will be coming over from T4 on the Heathrow Express.
Also, I didn't see an ATM machine anywhere on the map in the arrivals hall at T3. Is there one?
