Hey Stephen,
I believe what you’ve described is definitely achievable using the Event Aggregator. You have a valid Event Aggregator license, so grab it from your License Keys page and input it under your WordPress > Events > Licenses ‘Event Aggregator‘ field and give it a shot!
If the events are all on one singular Google Calendar, you could do it all in one import. If you have multiple calendars in your Google Calendars account, just grab the calendar URLs and import them individually.
I hope this helps answer your question and let me know if you have any additional inquiries or comments. Take care and have a great evening. Cheers!
