Hello!
Thanks for your feedback about the trip with us.
Of course, nobody can promise to see the manta rays during the trip. It is wild nature and the chance is depending mostly on the weather conditions.
And yes, it is true that in Manta Bay can be a lot of people which we always tell everyone in advance. Nusa Penida is one of the easiest places where you can meet them and it attracts a lot of tourists.
We do our best to make your experience as best and smooth as possible.
Unfortunately, we didn't get from your message what was our fault and how we can improve our services to make you more satisfied.
Both - weather conditions and the number of people on the spot are not under our control.
If there is something that we can improve from our side, please send us a message by email info@freedivenusa.com.
We will be happy to read your detailed feedback about our service and of course dive with you again if you will be back in Penida.
