So my lovely P I L have offered to look after our children so that my husband and I can remember what each other look like. We have Friday to Sunday. We want to make as much use of it as possible and would like to find a nice hotel with a not too long a drive of London. Budget is probably around £500 for two nights. Any Recommendations springing to mind? I would like to think that we are going to do cultural things during the day but I suspect we will just spend all day in our room revelling in the lack of children! Not that fussed on spa things etc - nice grounds would be ideal. Any recommendations?
