This is not specifically a Session idea, but a suggestion regarding the block of rooms for the conference. In 2017, I was easily able to reserve my room at the discounted rate for a few more days after the conference.
For 2018, they said that they could not provide the 2 extra days I requested at the discounted rate. JW Marriott suggested that I make a suggestion to the organizer of the event - to extend the discounted rate block for the rooms.
So this is my suggestion - that we can stay a little longer as part of the same reservation block. They had to do 2 separate reservations for me just to get me booked (and at a higher rate for the extra couple of days).
