The Bath road Hotels did indeed lend a touch of jet set glamour to lads and lassies from the LHR area . As you say the Aerial with a nice bar was one and the other was the Sheraton (?) which had an internal tropical styled swimming pool along with suitable themed bar . My brother worked there and saw someone actually manage to do the classic accidental step backwards into a swimming pool in full business attire. It was a good place to impress young ladies on a wet misty February evening, especially as many of the traditional hostelries of the area were more suited to a game of darts or a bit of agro (in the vernacular of the day) than romance.
