I'd imagine QR will expect you to minimise the transit time in the spirit of the conditions they attach to providing accommodation. For them, it will be hard to understand why you wish to leave London on a day which avoids an efficient to connection to the non-daily fight from Doha to your destination - unless you are gaming a 24H stay in Qatar.
I'm sure you have a pressing need to leave London on the date you have selected - and if QR pushes back on providing a hotel, I'd go for +Qatar, or simply book my own. Four-stars like the Holiday Inn start at around £50: the splendidly located Najada £90 or so
