Princess cay stingray excursion anyone?

We are thinking of doing the stingray excursion, it seems fun and also educational which we are trying to make this experience like for a 15yro. Has anyone done this excursion and could tell me about their experience. Was it worth it? How long was it ? How far away from the actual tender area and accessible?

Thank you!

next cruise 12/9/18 Liberty 😁

I'd also be interested in hearing from someone who'd done this. Thanks in advance -
