Having rang them up they seemed very unsure about what hotels they go to but seemed to think the drivers would go to any
Not a very satisfactory answer from them. Having had a bloody minded driver one year who drove straight past my hotel (where my friends were standing outside waving) , because it wasn't one of his regular stops, I would be a bit wary. I admit it's the only time it has happened though and a smile and polite request has usually worked.
