We will have to stay off site at a hotel the first night since we decided to come a day earlier and there were no tent sites available to extend our reservation in that direction. My plan is to get up early go to FW and check in and I guess leave our stuff in the car while we go to a park. Then come back to FW later in the day and set up our campsite. I don't know if we'd be able to get to the park at rope drop if we do this. Can we check in at any time after midnight on our day? Thanks.
