I believe no expiration period CAPT RANDY THE BEST DO IT !!!
No we just went they said never!
I went a month ago and they said that it never expires, not even in 50 years.
I was there in June and they said it never expires until you see dolphins, even if that was 10 times. You should've gotten an email after your tour on rescheduling it. If you don't have the email, give them a call. I'm sure they'll get you taken care of!
When we were on last month, they said the voucher does not expire
