Excellent
I went with my husband, not to snorkel but to go on the boat. When we arrived the manager told me that it would be very bumpy in the sea conditions and said if I wanted, I could stay at the dive centre or they'd take me back to the hotel. They also would refund my part of the booking. So, I stayed at the centre where I was made to feel very welcome, given a bottle of water, advised that they had sent the refund request to Tui and even gave their WiFi code to use. A great day had by both of us.
