We just booked POP for 7 days in mid June. Every other trip we've planned ourselves, but with all the changes taking place with Covid, we decided to use Mouse Class Travel this time. So far, so good!
We are super excited -- but also hoping that a few more things are open (Restaurants, Ratatouille Ride) by the time June rolls around. Glad we'll have the Park Hopper option for 2021. Would also be nice if masks were more optional by then. I'm predicting capacity will be at 50% by then. I'm guessing Disney has plans to continue to ramp things up so that they can be much closer to 100% by the time the 50th anniversary rolls around.
