2 weejs on your own with 2 under-5's is tough for many, it was for me.
Harder if you've no cash!
I have been there, and found it essential to be out of the house by 10 every day.
Make something into a "project" like walking to the shops to buy bread, go to all playgrounds within walking distance, go to the river/lake/pond to throw sticks or pebbles the furthest. Go to the library, get on the bus to nearby town, and buy a donut. Anything really.
Do picnics if weather allows.
Go put to see who can find the biggest pieces if flint/sticks/stones.
Scour local papers/websites for free activities.
Go see your family, just dose kids up with the appropriate amount of Kwells or Stugeron. When travelling make sure they have just eaten, but NOTHING sweet and NO juice. A cheese sandwich and water are ideal. Keep car very cool and make sure they are not hot (coats off) and distract them with an audio book. Mine get very travelsick so feel a bit of a pro.
In the afternoon plonk them in front of a film/tv.
Having a sort of schedule really helps.
