We just returned home from spending two nights at Indian Springs. The campsite we originally reserved (#59) did not have enough flat space for two tents but they were very nice about letting us pick a more suitable area. We also got in on the Saturday Night Fish Fry ($7pp) and the Sunday morning Pancake Breakfast ($4pp). Both were very delicious! Another thing we really liked was the family atmosphere. There weren't any huge party groups that kept us up all night. My only complaint is about the bathrooms and showers. The bathrooms are so very dimly lit you can hardly see and most of them had huge spiders/webs. The showers were warm (if you paid $1 / 5mins) but again needed better light bulbs. It really wouldn't take much to keep up with the insects, put in brighter lights, and a decent shower head.
We LOVED our float trip which took us about 4 hours with stopping about 4 different times.
