Seasonal Internet Access Plan vs. Seasonal Convenience Plan

The Xfinity site describes two types of Seasonal Plans for Internet.  The Seasonal Internet Access Plan ($29.95) is supposed to provide low speeds for Internet-driven devices like Ring cameras.  The Seasonal Convenience Plan ($8.00) is supposed to only allow you to keep your email address, with no Internet access. 

The online enrollment form does not provide any way to choose the Seasonal Internet Access Plan -- it just defaults to the Convenience Plan for $8.00/month.  I called Xfinity and both the Agent and Supervisor said that the Convenience Plan for $8.00 will still provide Internet access at the lower speeds and will NOT turn off the Internet.  [They do not have the ability to choose the Seasonal Internet Access Plan.]

I'm still not sure I believe what they are telling me.  Does anyone have experience with this?  I'm trying to avoid an unpleasant situation on my seasonal plan start date of Oct 1st with possibly no Internet service.
