We will be travelling from Heathrow to Frankfurt to catch a bus to Trier for the start of our tour.
Our flight arrives 11:05am. I have the option of catching either a 1:15pm or 2:15pm bus.
I think our flight lands in Terminal 1, whereas we'll have to catch the bus from Terminal 2. I also don't know if we have to go through Customs or Immigration since we're travelling from within Europe (unless the UK is different). So given customs, walking/transfer times, and possible delays, which do you think is the better bus option?
Thank you.
