I would appreciate advice regarding a side trip we are planning with our two children (13 and 11). We are leaving Heathrow car rental at noon and driving towards Wales. We've spent several summers visiting beautiful England (husband is English with a Welsh mum), and now we are taking a quick trip to Wales. We're thinking of Stonehenge and Salisbury (animal park) day one. On to Cardiff day two. Wales day three and straight back on to Windsor (M4) on day four. We'll be in London with family after that. Suggestions regarding places to stay and see on the way to Wales? We were considering the Marriott in Wales? Thank you.
