Hi,
Thanks for the interest in our plugins.
I can help answer your questions.
WooCommerce Tickets creates tickets per event so you could create a ticker for each day with the 100 day seat limit.
We do not have features though to purchase a weekly ticket and at the same time reduce the stock of each individual day.
It could be possible with a customization, but that is beyond the support we can provide.
Let me know if you have any follow up questions.
Thanks
