Wasting money with Large Meeting option. Alternatives?

[IKO]

I just read where it says "If you want to invite fewer than 500 participants to a scheduled or instant meeting, you can do so without having to purchase the Large Meetings add-on or a webinar license. Learn more about inviting others to join a meeting."

We have purchased the Zoom Pro, but there may be a time or two we need more than 100 participants but less than 500 (more like 200-300 participants).  So we also purchased the add-on Large Meeting, but we're wasting money because so far we haven't needed the Large Meeting since the 2022.  So based on what I read, we don't need to Large Meeting add-on...just invite others to join.  Is there any charge at all for 101-200 participants? We just send the Zoom link meeting to all 200 participants and everything works as normal? Any gotchas?
