The title should say it all. I booked my first visit to London and reserved a room for last night on points at Hilton Terminal 4, as we have a 7:45 AM departure on United from terminal 1. I had concerns about timing using Hoppa bus from the other hotels in that it might take longer than we would like that early to terminal 1. (I assume we need to be there at T1 more than 2 hours before departure.) I thought it would be a relatively simple and speedy matter to walk to T4 and take the Heathrow Connect to T1. Should I expect it to be simple and quick? I see Hilton offers an option to transport us via car to T1 for 20GBP. (There are two of us.) Would that be faster, meaning we could sleep later?
