Hi Erica,
Thanks for checking out our plugins!
It sounds like the Ultimate Bundle will work best for you here…it includes everything you mentioned, besides Image Widget Plus. As far as reservations, you can take free reservations with Event Tickets, which is free itself (and is also required to run Event Tickets Plus).
To add Image Widget Plus to the bundle, can you please contact us using the form on our contact page and selecting “Help accessing my account”? We can get you taken care of from there.
For your users to export events, we do have buttons on events by default that will allow them to export to Google calendars and iCal (see screenshot), and an export button on the main events calendar (see screenshot).
Please let me know if you have any other questions, and we’ll keep an eye out for your email regarding the bundle!
Thanks,
Jennifer
