Nassau 1/2 day shore excursion booked thru Viator?

I'm wondering if anyone has taken the Nassau half-day shore excursion boooked via Viator:

I'd like to hear about your experience and how reliable the local company is.

Thanks in advance!

We have this tour booked for the middle of Sept. so haven't been on it yet. It uses Tyrone Wilson's V.I.P. Taxi and Tour Services. They have reviews on Trip Advisor.

We have used Viator before with no problems.

Hope this helps.
