We want to book an overnight stay in a couple of week’s time. No reason to think we won’t go, I suppose unless we happened to be poorly or something. It’s £30 more to book the ‘amendable’ option. Would you spend this or not?
I guess it is good to have back up but when I’m 99% sure we will go, that £30 could be spent on breakfast out the next day.
YABU - I’d always book it
YANBU - no, waste of money
