Not in the UK, I don’t think. They’re nowhere near as generous cancellation terms that you get in the US. But the packages are in some ways better. I think.
Yes, you’re booking from the UK complicates that equation quite a bit I think as it sounded like your room only booking had a relatively nasty cancellation penalty comparatively. I think for the US there’s no penalty on a room only cancellation if > 5 days by comparison. But yes, I think overall your deals sound pretty good with the 14 day ticket options which include park hopper and the free photo pass. Guess they need to make it worth your while given the high cost to fly over…
