We had my son's 8th birthday there and everybody loved it. 25 sounds like a lot to invite though and it can get pretty chaotic there on the weekends. There is no supervision provided by the park--the only supervision is provided by you. I think we had 8-10 guests and I felt like we had our hands full (although they were active boys). It is generally recommended you have one guest per year of the birthday child (so in your case approximately 7 guests). There is an enclosed 3-story playground (although 7-year-olds can open and run out the doors), kind of like a super-McDonald's playland, and there is a gym with a jumper that the kids usually have access to (although they didn't for our party because of a wedding). You also have use of a party table in a community area. There is a toddler area in the playground. However, they no longer have the swings, etc. that they used to have a few years ago. The party tables are in that space now. There will be more than one party going on and the park and playground remain open to the public during the party. I would significantly shorten the guest list or get more chaperones. We found it to be a good value and cheaper than some of the other similar places to have a birthday party. Have fun.
