I reserved a group of 10 to do the waterfall rappelling on a specific date. I got confirmation via email that the spot was ours and received several emails in preparation.
Then I got an email from them saying that, because of "an incident" that had happened, they needed to inform me that they can't take people bigger than a 38 inch waist and, if you slip and fall into your harness, you need to have the strength to pull yourself back up on the rope.
I emailed them back that all was good and asked for a phone number where I can give my credit card number. Here's the thing: to schedule, you can email one person, but the phone number they have on the site belongs to the guy who actually takes people out to the falls and he will tell you he doesn't do reservations, so I had no number where I could give my credit card info.
After an active back and forth with the scheduler, and the date confirmed via email several times, I heard nothing from them for almost a month. I emailed multiple times, no answer, and every time I called the phone number, the mailbox was full. Finally I got a hold of the guy on the phone and he said he was at the waterfall and doesn't do the scheduling, that I had to email the scheduler. I said I couldn't reach her and he said he would check and call me that night. No call.
I called him again and he just said, "I just do the courses, you have to talk to her". Finally I got an email back saying that my spot had been booked over and was no longer available, but I could get a spot in September. We had been confirmed since June and everybody was eagerly awaiting the day we would do it.
To get this information only 10 days before our event was incredibly disappointing. I could not trust this organization and will not recommend them to anyone as they clearly are having organizational problems. Also, it's kinda shady if you can only email the office and the number you get is someone's cell phone and he won't do reservations.
