That sounds similar to me going 4 days without my laptop, though my internet use was very basic. Here's some suggestions that I have that you can do:
- Play some videogames. You should have quite a few and take interest in whatever's your fancy, even if there's no net at all.
- Watch some movies, or see what's on TV. Providing you got a DVD/BluRay/LaserDisc/VHS player (lol multiple colors), you should be fine to flick through what you have.
- Take up crafts. Sometimes when I feel really inspired, I draw it out. I also used to do cross-stitching a few years back as well.
- If the rain subsides, go outside and go for a walk. It's a pretty location, so it's best to take advantage of it when it's not so wet :)
I hope these provide a good starting point. Just hang in there!
