It was a great day out and communications with the team were excellent and very friendly . I booked a morning tour but ended up on a full day tour,visiting an extra cave .( at no extra charge) I think happytovisit.com are an agent who then "contract you out " into another tour group. This worked out great for us.
The caves and Porat beach were lovely and worth a visit .
