Sorry, I don't think I'll be able to help you as what I'm looking for is confirmation that they received my reservation. I will not have a pickup time as the only direction I'm using Mears is from MCO - Pop Century.
For the return trip I booked with Sunshine Flyer (which starts their service Feb 1, 2022) so that I could compare the 2 companies.
I ended up hanging up on Mears after being on hold for more than 30 mins. Emailed instead. Will see if I hear back from them or, if the confirmation email is sent.
