I think the answer to this depends a lot on how you are living now. Are your kids back in school? Does your husband go to work outside of the house? If the answer to these are yes, then Disney will not be much different. Most of it is outside and for the most part people do a good job wearing a mask. That being said, we went in November and we just returned and the difference in attitudes is night and day. In November everyone was vary attune to social distancing and wore the masks religiously. Two weeks ago, social distancing was much more lax. Sure there are markers for lines and some people follow them, but some people don’t. Honestly, this isn’t much different than the grocery stores around my house so it’s not a huge surprise. But people are also much more lackadaisical about masks now. I saw TONS of kids without masks, eating in line etc (which is technically not allowed). Some adults were also breaking the rules as well. I’m not super alarmist, so someone more than 6 feet away from me without a mask isn’t going to make me upset, but it is what it is. In November I saw one person our entire trip remove their mask at an inappropriate time. Attitudes have just changed.
Also, crowds are not low anymore. The current capacity limit at full capacity feels like a regular to slightly busy park day. Social distancing in queues has pushed people out into the walkways which make walkways crowded. In November our trip was great and crowds felt low. Two weeks ago was insane. I was shocked how many people were in the parks and they were all from other states.
All that being said, June could look wildly different than now. Cases are already plummeting and more and more people are getting vaccinated. It will likely be a while before kids get the vaccine, but a lot of adults could be vaccinated by then and that is great news. Personally, I would hold on to your reservations until closer to your dates and reevaluate.
In general, though, if you are still very strictly quarantining then Disney isn’t the place to be. If you have ventured back out, but are still concerned about safe ways to do it then Disney is doable. For the most part you can control exactly how much you are comfortable doing and if you are uncomfortable, it’s easy to find an uncrowded corner to take a break!
