How much does it cost to stay in the Quality Inn Hotel for one day?

I would imagine you are referring to the Quality Inn Hotel, as in the hotel chain based in the UK? If so, you would be looking at paying between £40 - £50 per night, which is based on purchasing Double Room, and to get a room at that sort of price, you would need to book up a week or 2 in advance using the internet Special Rates, sections on their website. I'm will actually be stopping at one of their hotels next week, but managed to get a good deal through sites like Groupon, where they "Group Sell" tickets at dirt cheap prices, in order to keep businesses afloat through the quiet patches I would imagine. Just quickly had a look and can tell you that booking a room about 2 days in advance, would cost you just £40.00 instead of £100, and that would be for the Standard Double Room, which sleeps 2 people, and obviously, that price does not include breakfast should you need it, but it can be added on to the price of the room for £7.95 per person. (May sound dear, but it's apparently a Full English Buffet Breakfast) so you can virtually eat all you want.

The rate's I've stated, are based on the Quality Inn Hotel, in Birmingham, in which you also get free access to the Swimming Pool, Jacuzzi, Sauna, & Gym if you have the time to do it in a day.
