Been there, done that ;)
This 2 test requirement for summer travel, although not unexpected, really needs to be looked at what test type they accept.
If they don't permit the lateral flow tests, then something needs to be done to make PCR testing more affordable.
You cannot expect travellers to be coughing up around £125 a pop for a PCR test, particularly when they can be done abroad for a fraction of that cost.
If nothing changes on that front then things like short breaks, weekend City breaks just aren't gonna happen, as who is gonna pay £250 for 2 tests for a £300 short break to Spain?
Myself and a mate have got a week in Kos booked for the August bank holiday weekend...7 nights, all inclusive...£565pp. A lot can obviously change between now and then but should testing still be averaging about £125 a test, I'm not sure paying 250 quid to go on that holiday is worthwhile or not. By August I'll be desperate and will likely just pay it, but if the holiday was a little cheaper then I don't think it would be worth it.
Likewise if the holiday was more expensive and the tests represented a smaller %age of the overall cost then it would likely be worth it.
It's really bad for families with older children.
