In July the weather is warmer and we will not have problems like rain or excessive cold. Besides this, we can tell stories or do other free activities at night.
About cooking I could help you in any way you need. In my opinion we can also bring canned food, that is more easier to prepare.
In the days before we go to the camp we have to go shopping. We can reserve a week to buy things like tents, sneakers, clothes and canned food because I do not have the necessary equipament to stay an entire month camping! Besides that I would like to meet the people we are going with to the camp. [I would change here, to "I would like to meet the people we are going to the camp with...but then, it´s me, my way.]
The last time I went (to) your home I just met Luisa and Gabriel. Now/this time, we could go to the park near your house or to the movies.

This way, it seems like you somehow wanted to say that you went to your friend´s, but you are saying that you had another option to go out with the kids (at the time).
Let´s wait for more comments.
