We are due to arrive in Orlando on the 7th April and staying just over a week. The current Park bookings availablity for that week (and pretty much most of April) seems to be Epcot only, there is a random day here or there for AK and HWS and only 1 day available for the week we are in Orlando, no MK availability for the entire time we are there either 
Ideally we would have had all this booked way in advance but we are coming from the UK, and this is probably the 3rd time we have had to rebook the flights & hotel due to covid and closed borders. We have to take a covid test 24 hours before the flight so essentially we may even get refused entry and hence why we only want to book once we have arrived into Florida.
My dilema is that ive heard that if you have the park hopper option that you can then 'park hop' to another park from Epcot, but only from 2pm onwards, and that obviously its not guaranteed either. So i could be paying just under $2,000 for the passes (2 adults 1 child) for the week and only end up going to Epcot everyday (depending on availability). Just wondering if its looking likely that park hopping will most likely be available as when i've checked previous blog posts and comments about park hopping it seemed like by 2pm all availability for all parks showed up on most days (except maybe some special events).
any advice at all would be much appreaciated. Many thanks
