My DD-15 and I got back yesterday from 6 nights/5 days and stayed at Caribbean Beach. I would like to start off by saying I think Disney has done an amazing job putting all of these safety measures in place. We knew that going into this trip it would be different from previous trips and were okay with that. In the end, I enjoyed this trip a little more than usual because it was more relaxed. We took mid-day breaks some days, and we didn't try and do rope drop every day, some days we slept in and got to the parks around 11am. Usually, we are the people that will go to a park and then another park and be gone for 15 hours in a day, but not this trip. Not having FP, which normally forces you to plan everything around it, was really nice. You know going into it that you will wait about an hour for all of the popular rides, if you don't do rope drop. Yes, this means you typically can't get off a ride and immediately get back on like you can when you get FP after FP. As long as you know ahead of time the popular rides will take an hour, you will not be disappointed.
Going through security is awesome now. We did not have to take our stainless steel water bottles out of our bag, but we did carry our phones in our hands as we walked through. I hope they never go back to the old way of digging through everyone's bags. Typically, once you get inside the temp check tent, it will take no more than 2-3 minutes to go through security and scan in to get into the parks. This was one of the best improvements COVID has brought to Disney.
We stayed in a pirate room at CBR and requested no mousekeeping. I will freely admit that I am a germaphobe and wiped down all of the hard surfaces with Lysol wipes that I brought. The resort was fine, we liked staying there because of the Skyliner. HS is our favorite park so it makes it super easy to go back and forth. CBR food options are limited to just the Centertown Market and Banana Cabana so they both get busy.
If you don't know how to mobile order food, look into it now. I actually ended up loving this and had not used it before. I was hesitant to use it before because I didn't want my food to sit and get cold but you tell them to "prepare" your food once we get to the restaurant/counter. Do some research before you go so you know what QS have mobile ordering because not all of them do. The grilled cheese sandwich at Woody's Lunch Box was really good, but you need to order early in the day for Woody's to get a lunch time slot, it's a popular QS.
Overall, I would say the mask wearing is good. There will always be those people that are reminded to wear them properly and then just let them fall back down when a castmember is looking away. The CMs do the best they can and do remind people politely to fix their masks. In my observations, I would say that the middle school age group are the worst offenders. They are old enough to know better but often their parents don't say anything to them. These are also the same parents that don't seem to know that their mask should cover their noses. If you decided to come to Disney right now, you agreed to wear a mask. If you don't like this rule, then don't come right now. We chose to come to Disney because of their mask mandate and enforcement, respect the rules.
In general, people are good at following the social distancing in lines. We had one case where I politely asked 2 teenage girls behind us to stay on their line because they kept getting within 6 inches right behind us. They were on their phones so I think they just weren't paying attention. There were a few times where you just had to turn around (not saying anything) and people got the message. Sometimes we all just need to be reminded because we have not lined up that way all of the previous years, it's so easy to forget.
As far as the buses go at CBR, we had really good luck getting to and from AK and getting to MK. When we tried to get a bus from MK back to CBR at 1pm on Sunday, that was not great. When we got to the bus stop there were so many people that we had to wait outside of the gate. The first bus came after about 5 minutes but could only take a few people. Knowing this was going to be a long process, there were lots of strollers and families, my DD-15 suggested we get on a bus to HS instead and then take the Skyliner back to CBR. We ended up doing this, but I would say we should have stayed put. I think we would have gotten on the third bus that arrived at the same time we got on the bus to HS, oh well. (We had no bus experience for HS and Epcot because you take the Skyliner from CBR to those parks.)
General Tips:
If you have smaller children attach their mask to a sunglasses holder so the mask can just hang around their necks while eating or drinking. I wish I had done that for myself because I hated putting my mask on the table or chair when we were eating.
Bring hand sanitizer and have it hang off your bag so you don't have to dig for it every time you want to use it.
Bring anti-bacterial wipes so you give yourself a break from the hand sanitizer which I find can leave your hands sticky after several usages. I brought a small empty ziploc bag and labeled it "Trash" so we could put the used wipes in it in case a trash can was not around at the time.
Bring a cooling towel for the hot days. They sell them at Disney, but you could get one much cheaper outside of the parks. It got really hot this week waiting for different rides since the lines have to be spaced out and often are in the sun at some point.
That is all I can think of for now, hope you find this helpful.
