Just returned from 3 nights at Disneyland Paris. Great holiday, tests were an issue though.
Used Loxamed - which is the company employed by Disney to do all on-site testing. Got 3 out of 4 results back in 7 hours which was impressive. What was less impressive was that 1 of the results had my wife's maiden name (note to others: don't bother putting your birth name on any form as this is just another opportunity for somebody to screw something up!) and mine didn't arrive at all.
We went back in the next morning and fortunately they were very helpful in sorting it out - but even they had to call the lab about three times! The test certificates my wife and I got did NOT have a QR code, and I did worry about this, but EasyJet were fine with them (after all they did have full names, test times, result, lab-headed paper etc.)
Still, it will be a lot easier when the test to return home is scrapped in October.
Remember the days when you could just jump on a plane and go somewhere?
I miss those days :(
