DHs birthday next weekend and I’d like to do something to celebrate with the kids. Being completely transparent we are not the roughing it type of family but I don’t want to spend lots of money staying at a hotel, I’d like to do something a little more rustic and fun for the kids. We are in Hertfordshire so ideally not hours away from there. Ideally some sort of hot tub, toasting marshmallows, playing in the stream. Any recs would be much appreciated 🙏🏻
