If it's anything like what I saw in Old Town Alexandria during phase 1/2, the park may have done really well opening up England/Scotland/Ireland to walk around and have food/drinks. People just wanted to get out - walk around, get some ice cream, have a drink, etc.
Even if they didn't make money or took a small loss, the customer goodwill and trust with the government that it's safe to operate would be worth the costs. They are playing catch up now having to prove it's safe to operate, when instead they could have been doing that 2 months ago. Universal and Disney did the right thing piloting opening with their restaurant/shopping districts as a proof of concept on what reopening would look like and it paid off in the park's full reopening.
