Hi, regarding the issue of you in a motorhome staying close to your brother in a cabin, my understanding is that there are no loops with both cabins for guests and regular camp/motorhome sites. However, the best you can do is for you to request a site in loop 1100, and get your brother to request a cabin in loop 2100. This would be the shortest walk you could get between such regular vs. cabin loops. Also, if you really got lucky your site would be near the back of 1100 and their cabin would be on the north-east side of loop 2100, and you might be right next to each other (I stayed in a cabin in loop 2100 in the year 2005, and one morning I waved hello to someone staying right behind me in a motorhome in loop 1100).
