Xmas bubbles

[MyNameHasBeenTaken]

I know things are likely to change a few times between now and xmas.

But does anybody know there latest rules for meeting loved ones over xmas?

I am single mum to 2 kids. One under 12, one over.

My sister lives alone.

My mum lives with her new partner.

That's 3 houses

We all want to go and see my grandparents. That's household 4.

But only 7 or 8 (depends on step dad) people. Usually 7.

Can we do this?

We would all isolate for a week before travelling.

We are all in england.

We are not decided

We are torn between wanting to see family but not risk anybody.
Same as most people I guess.
Gp booked the hotel in the summer.
Their view is we are going!
Nobody is in a bubble, but any of us could bubble for gps.
Wrap up warm and be outside most of the day sounds good

We could all wear masks inside too.

I would op?
