Shamelessly posting for traffic as I'm at a loss as to where to book to take DH away for a couple of nights for his 40th. I've got it into my head I want to stay in one of those amazing treehouse hotels but it must have a hot tub and be no more than 3 hrs drive from London. Ideally toddler DS would cone too but if it doesn't work for him then the grandparents must step in. Budget around £600 for 2 nights in Feb.
Or inspire me with other romantic quirky hotels / places please Mumsnetters! Think along the style of The Fish rather than Crazy Bear!
