Hi Chiara,
How exciting! You are going to have a wonderful time at the
Campsites at Disney's Fort Wilderness Resort. The
Preferred Campsites are located on the 100, 200, and 300 loops. They are located closest to Pioneer Hall,
Trail's End Restaurant and the marina. However, they are not
Premium Campsites. These top-tier sites, which you reserved, are located in loops 400-1400. You will be in a site with a better, longer concrete pad and will be closer to the pool and the trading post. There are several online blogs which are dedicated specifically to all things Fort Wilderness. You may want to research the Premium Campsite locations to see if there is an area which appeals to you more than others. You can then put in your request to be on that loop. Requests are never guaranteed and are based on availability at the time of check-in, but Disney always does their best to honor requests.
Wishing you magical memories,
Kaylene
