Just realize your mileage may vary when requesting space. We had a terrible experience on the safari and felt very unsafe last week. Despite being a walk-on they were seating every row, so I asked for space and the CM kept saying "but there's dividers for safety", and i kept saying "but we would like a row between us and others because we don't feel safe even with the dividers." After 3 requests she finally said ok and directed us to row 7, which we took because there was no one in 6 or 8. As soon as we sat and got settled, she loaded people in those 2 rows (it was definitely the same CM) and as i was saying to DH we should get off, away the vehicle went and we were stuck for 20 minutes (or maybe more - we had a rhino traffic jam!).
To add insult to injury, row 9 was left empty; they could have put us there, and the row 8 family in row 7, and had the same number of people in the vehicle but complied with our request.
The row 8 family had an unmasked child right behind me who kept leaning out of the vehicle and forward so she was almost even with us (I'm shocked the driver didn't say anything - that kid was out of the vehicle from her knees up, only being held by one adult arm), and another adult in their party took her mask off and the driver said nothing so finally i had to ask her to put her mask on. I am not confrontational and this was way outside my comfort zone. The kid looked under 2 so not breaking rules there, but seating an unmasked person behind someone who's asked for space seemed pretty uncool on the CM's part, and then between the kid leaning around the divider and the adult unmasking, it was very uncomfortable.
I know many people on here have reported having luck asking for extra spacing, but it clearly doesn't always happen. Just be prepared to stand up for yourself. We had similar issues at FoP that day (unmasked guy behind us for 30 min in line and no one said a word) and the next day at epcot (placed every row on LwtL and guy in front of me took off his mask, and again i had to ask him to put it on). We actually skipped our next park day after that because we felt so stressed about the lack of safety, though we went to MK a couple days later right before we left and it was much better.
I'm sad, because we were going to come back in feb or march, but after those AK and EP days, there's just no way I'm setting foot in the parks again anytime soon. We may do a resort stay at the FW cabins, but that's about it. I think disney is really dropping the ball on safety; in addition to the incidents above, there were just scads of unmasked people and not enough CMs to monitor. They need to hire back CMs and put them on enforcement and monitoring. I loved how every DVC sales booth had at least 2 CMs shooting the breeze, but there weren't sufficient CMs to monitor the crowds or rides. You can tell what's important to the company, and it's not safety.
Sorry for the novel. We were just really disappointed and surprised at how many unmasked people there were, and especially with the CM's attitude at KS.
