Replying to Timberline public park (spring pass) vs. private parks

Going to be at timberline public park for the spring pass and was wondering how different it is from the parks that aren't accessible to the public? Anyone know what the conditions are looking like now/what they usually look like during early-mid May? Ballpark size of largest jumps, number of features, number of runs, number of lifts open during spring pass would be helpful.

First time going to oregon so the more info the better, thanks. Btw I'll be there may 7th-20th, if anyone wants to ride together hit me up around that time
