I went with my missus to a place called Forest Rise Eco Retreat.
Because it is winter/cold they were doing specials so it wasn't that expensive.
If you want a romantic sorta stay it's perfect.
Some good things are
-Big spa, with glass roof to check out stars, also candles.
-Mountain bikes are provided, there are several easy tracks around the property through the forest, good fun. The house has binos, and bird/animal books if that is your interest.
-No formal check in. We didn't see a single other guest the whole time. All the houses are hidden from each other in the bush.
I can't think of a single bad thing. (Apart from reading through the guest book, and "We felt like naughty enchanted ferries" had been written by "Richard and David"... haha)
We paid 660 for 3 nights. So 220 a night is only 110 a night each.
