Far from it -- that's quite kind of you to offer. We have few obligations over the holidays, and of course Barty is still recovering, so whenever you have the time would be lovely. The Floo address is 'Cottesmore - New London' or 'Cottesmore Steading' (either will work, but simply 'Cottesmore' will wind you up halfway across the country) and if you arrive when I am not home, I'll leave word with the elf that you are to be welcomed.
