Staff are great trip dissapointing

The staff was the best part of the trip entertaing and friendly. The snorkelling was disappointing to many people in the water and not much to see. The islands are beautiful though a victim of tourism with us been 3 of them.

Too many people

Too many people on the beaches and dive sites. Good organization, though. Engine failure of the boat on return, well managed: transfer to other boats. Attentive and friendly staff.

Too crowded

I could not fault the tour guides and organisation of this company but this is a mass produced tour day with hundreds of people descending on the islands at the same time. We left our hotel at 730am and returned at 530pm. We had 2 x 30mins sessions in the water snorkelling all day. It wasn’t enough. There was no time or room on the beach to set up and relax and snorkel at your leisure. The weather wasn’t favourable which meant the boat ride each way was almost 1.5 hrs and extremely rough (do not recommend if you suffer sea sickness!). We were lucky enough to see one turtle, the poor thing had nearly 100 people trying to see it and yelling at it either from in the water or on the boats. Such a shame as the marine life and water was absolutely magnificent, we need to find a way to enjoy it without the crowds.
