I don't think there's a cats chance in hell that travel (and certainly not non-essential trips) will be ok by the summer. Even if Italy is past the worst, the U.K. is unlikely to be.
DH saw the writing on the wall and cancelled our planned May trip to Sicily before the balance was due near the start of February. Lucky to only have lost the deposit. That was before Italy had emerged as an epicentre.
DD has already resigned herself to the idea that not only is any travel with her friends this summer unlikely (except maybe something like camping in the UK) but that there's a distinct possibility that the Xmas university ski trip will be off.
If by some miracle all of Europe including the U.K. gets this stamped out in the next couple of months there will probably be some fantastically cheap offers.
