Ah, I see you have been in her living room
As everybody says, the amperage is far more important than anything else, so nothing with a heavy drain (irons, kettles, curling tongs, heaters are a big no no) but small devices you should be fine.
Daisy chaining is never a good idea, there are some decent "tower" type multi plugs out there, but even then you have reached a lever that could be considered excessive.
Can you not have some new sockets fitted running off the double you have or any in your back room ?
You could always run a "power rail" around your room.
You have made me look at my "TV corner" now, yeah, might have to do some re-wiring there, do as I say, not as I do
