When you create the plan you can enter a goal event that the plan builder will end your program at or just let it run through the whole year with no set goal (just a focus).
I would just skip the final week and get on the bike as much as possible while your family visits. If you can maybe get an hour or so in in the morning before people wake up then try to do that but I wouldn’t sweat it too much.
Then depending on how much work you get in while your family visits I would either take the recovery week as scheduled (if you get a descent amount of time on the bike) or maybe add a couple of harder efforts earlier in the week to open up your legs a little before the next block (if you don’t get on much).
If you don’t have an event in the month or two after this break then I wouldn’t worry about the missed week too much. Just enjoy the time with your family and get on the bike as much as you can if possible then get back to work when things are more consistent after the holidays.
