Hilton Hotels in the UK do some good weekend breaks. If you look in many of the papers, perhaps the sunday papers, you can see a lot of their deals.
For example 2 nights in say the Hilton Bristol, with breakfast both mornings, and dinner on arrival night, is only 66 pounds per person, so about �132.
You can extend them to 3 nights or 4 nights if you wish.
Hotels can be cheaper, or more expensive, depending where they are.
That is for a quality hotel, AND many Hiltons have a living well health club alongside that you can use (swiming pool etc).
I am over 50 so Saga often send me details of Hilton deals. They say quote P38ML2 when you book for 2 nights, or P38ML3 for 3 nights or P38ML4 for 4 nights.
You can read more about Hilton delas for Saga people on this web site.

You do not need to be a member of Saga to use this ofer, just over 50 I think, but who is to know.
