Go to Account Settings, @Julie909, where you do have some control over how you are reminded of things. I say "some control" because I see I have 'text messages' checked in mine in all areas except promotions and policy, and yet I have never, ever, received a text from the system - only emails and push notifications. Try it, anyway. Might work. I agree that the guest-is-coming reminders get a bit much. Usually delete-able, but if a host had truly forgotten someone was coming, they would be a welcome call to action!
