That may help a little, BUT if they have too many users for the amount of bandwidth they have, it will be slow everywhere.
To see if the park's available bandwidth is the problem, run speedtests before everyone gets up, and after most have gone to bed (if you're a night owl), and during peak usage times. Run the test 3 consecutive times and average the results at the various times.
To do the test on your phone, turn off cellular (so you're not testing your cellular speed) and go to www.Speedtest.net On your laptop, simply attach to their WiFi and run the same tests. Note that the speedtest is .net - not .com
