I just hung up from talking to Pony at Blue Angel. I verified that I could dive with them during May 1-4. That four minute phone call cost me 60 cents. Imagine that it would have taken another three minutes for additional info, that would have cost me $1.05 on my Net 10 cell phone. As an aside, I had to explain why I was calling. That it was just a test. That perhaps took more time than had I really tried to reserve diving days.
No need to wait even hours to book airfare and hotel.
Email has its place but sometimes a more personal phone call is faster.
I used the number provided in an earlier post.
