Yes but u must pay, there is also a shop for all items u may need in cabin

The kayak for the double was 40/hr in which you go around inch island (definitely worth it for the birds and otters) the motorboat was 80 for I want to say 3 hrs but you can rent it for less. The Japanese bath I think was 50 and the hotub (1hr) is included in your stay with an additional booking for something like 20. While they do have a bar and shop you can bring all consumables with you and eat in your cabin which is fab! Definitely ask for a therapy pricelist too because the women are fantastic! But I second calling or emailing them because the staff can not do enough for you.

Plenty of privacy ....

My toddler was plenty entertained wandering around the paths checking out the bugs and picking strawberries, and playing down by the water near the boat shack. He also loved going out on the boat. Not bored, lots of fresh air.

I think they are a good age for it, any younger they are very limited in what activities they can do! However important to note that activities are an additional charge so may become pricey if booking for 3 or more for likes of kayaking and paddle boarding
