Hi,
I always stay in loop 1900 with my pet. It seems to be a bit more private with more trees, but for this same reason the sites are a little tighter to get into. You didn't say what type of equipment you have, but if it's a larger travel trailer or motorhome or even if it has a slide out you may want to consider 1800. I believe that's the one directly opposite of 1900 and it has the convience of the pet walk right there in it's loop with a little larger sites.
Have fun I may run into you as I have reservations for the end of May beginning of June.
Hope this helps...
