To add on, if you are going to book a hotel on Bath Road, there are free, public buses that operate from the 'Central Bus Station' (connected by walkway to T2, 2-3mins) to those hotels. They look identical, but simply board and there's no need to tap. Google Maps/(insert other public transport apps) will advise you on which bus to get, and where to get off, and vice versa.
Do not get the Hotel Hoppa as it charges a silly amount for the ride (considering you can get it for free) or a cab as they're more expensive, and and they would rather earn £100 by taking someone to Central London.
