I'm staying in Slough at the Holiday Inn Express which is right near the Slough train station for one night before heading to Heathrow, can anyone tell me the best way to get to Heathrow Terminal 1 on Sunday morning? My international flight leaves at 12:20pm on a Sunday.
I have found the train information, looks like it's £9.50 per person with a change at Hayes & Harlington, journey time 40 minutes getting us there 3 hours in advance. Is there a bus option as well? Cost? I'm guessing that I can't use my Oyster card so do we pay cash on the bus or pre buy the ticket? Thanks.
