I have a student event with 200 kids where I need my five staff to check the kids in and modify two fields of data. All kids must arrive and be checked in during a 30 minute window.

So, I need the staff to be able to simultaneously access a cloud-based list of students, click them as 'present',  enter their meal preferences and type their home address such that the data is collected in single place. Last year we had paper check-in lists and it was chaos! Is Zoho a good option for this?
