All I could afford wrote:
Only time I have done it (2 or 3 times) was when a group of friends and family (total of 4 families each with kids) were meeting for a weekend and the way the campground was laid out, 5 sites were clustered together and we all chipped in extra for the fifth site figuring we could spread out campers better and have a bigger " common area". Plus, it could have potentially been an akward situation if 4 of 5 sites everyone is together and then there's just you right next to them. I've been that guy and it was no fun
I think in this case it was in the best interest for everyone to take the extra spot. Can't see anyone arguing against that.
I'm not sure what to think about the OP's situation. I get it that the spots are small but apparently not so small that others don't want to use the campsite--else this topic wouldn't exist. I understand the desire to have more space but I also understand that space is often in short supply and at a public facility needs to be shared. Being able to pay more to get more is fine at a private for-profit facility, But it doesn't sit right with me at a state campground. No disrespect intended.
