Each year my family goes on a 1-2 week camping trip someplace in the country; this year we're considering Isle Royale. My children (ages 10 and 6) are veteran campers, but we still try to keep our hikes between sites on the shorter side (because they are still ages 10 and 6). I'm thinking about taking the boat to Rock Harbor and then hiking to Three Mile. From Three Mile we would hike to Daisy Farm, and from Daisy Farm we would hike to Moskey Basin. I would like to spend two night at each site (my understanding is that this is allowed on IR). These distances are 3-4 miles each, which is perfect for my kids, who like to make many stops to play in nature (isn't that the point?

My questions ...
* Is this route a good usage of IR? Or are there better hikes which are recommended?
* My understanding is that sites cannot be reserved, but that if they are occupied we can double up, is that correct? Any chances of arriving at one of these sites and finding a "no vacancy" sign?
* How are the bugs typically this time of year?
* Any suggestions from IR veterans?
Tx!
