Hannah only bows out of the excursions that require lots of work. She's more than happy to weasel her way into visits to bars and cave tours when the guests have requested a specific stew that isn't her (the infamous 1 Coke excursion).
I'm not a Sandy hater, but the bulk of her decisions seem to be driven by production.
I'm not saying this is Hannah's fault, but Joao really had no options. Taking Jack would have been useless -- he does no work, and leaving Jack as the only deckhand on the boat could have ended in disaster.
Was Hannah really complaining to Travis that she hadn't stopped all day on the day that she spent hours playing in the water? Or was it a new day and I was confused? I agree that it is shitty that they were up so late, but I feel like maybe it wasn't the day to complain about how hard she'd worked.
I really didn't think the guests were that bad. They were entitled but in an oblivious way, not a demanding way, and were generally very nice and grateful for the service (small tip not withstanding). They might have run Hannah all night, we didn't see it, but she was complaining about it, but it seems like it was just them being crazy and all over the place, not being mean and demanding. We didn't see a single complaint from any of them.
I'm another that can't stand the sound of Aeisha's voice. Her laugh-talking drives me nuts.
I'm not going to spend the effort on shit talking Jackoff. He puts in no effort, so why should I?
ETA: Watching the first 2 seasons of Love Island UK has really improved my ability to understand Jackass when he talks.
