My wife and I (seniors) bus from Heathrow and depart early next am from South Terminal. On later return in evening to arrive South Terminal. Would like minimum walking and max convenience for overnight stays. Have liked PI in the past and see 4 near the airport.
Grateful for any suggestions..
It looks like the Premier Inn that is closest to the south terminal is this one: https://www.premierinn.com/gb/en/hotels/england/west-sussex/crawley/london-gatwick-airport-south-london-road.html?cid=GLBC_GATGAT
As I’m sure you know, most Premier Inns are pretty consistent when it comes to what they offer, so you should be fine just getting the closest one to your terminal.
I regularly stay at Gatwick North Terminal PI. It is decent enough- basically a PI, comfy bed, good shower, working AC, etc. It is a couple of minutes walk from the terminal.
I realise you're using South terminal, but there is a fast people mover train between the two terminals which runs regularly and only takes a few minutes. And the North station is also a quick walk to the PI. So despite being at the other terminal, the North PI is well worth considering.
