My family and I stayed at Wakehurst, it had everything we needed for a cosy and chilled getaway. Lots of nice touches, just be careful not to have the wood burner going too strong before sleeping cos the top can get very warm - figured out how to adjust the fire and everything else at the dome through the helpful guides/qr code accessible videos provided.
Hot tub was amazing, they have it warmed up in advance when you arrive and the weather was good enough for us to enjoy the BBQ properly. Think our dome was a bit further away from the others, plenty of privacy. A lot of planes do fly overhead but if you're a stargazer, you'll get some great views at night.
Shops over at Edenbridge have everything you need for supplies and the area is very scenic.
Would definitely come back!
