Thanks for your last Marriott stay - enjoy this gift

That timing works well on my side, and I can keep the afternoon open for it.
If the meeting shifts a little later, that should still be manageable because I only have one call in the morning.
I would bring the notes from the earlier discussion so we can compare the two outlines side by side.
The main detail I still need is whether you want to finalize the schedule first or review the vendor list before that.
Either path is fine for me, and I can adjust once you confirm which one matters more.

Marriot Previous stay notice for recent guests   A guest follow-up tied to your recent Marriot stay Because you stayed at a Marriot Hotel or Marriot partnered hotel within the past year, you may receive a 2-pillow luxury cooling set provided at no charge. After the brief questionnaire is completed, you may also claim a 2-night stay at select locations at no charge. Program details This opportunity is available to you because you stayed with us or a partner hotel within the past year. One 2-pillow set is available per household. You will not be billed for the pillows or the qualifying stay nights. Total pillow allocation is 500, and this notice ends Tomorrow. View pillows + 2-night stay The questionnaire is brief and helps us confirm shipping and participation details. Once it is submitted, your household can receive the 2-piece cooling pillow set at no charge, and the included stay benefit can be reviewed for eligible select locations. Availability is determined by program scheduling for shipment timing, stay dates, and location access. What to know about the pillow set Temperature-managing fabric can help reduce heat buildup during the night. A smoother outer cover often provides a crisp, hotel-style sleep surface. Balanced loft can support the head and neck without feeling overly firm. Cooling pillow materials may help the sleep space feel fresher across the evening. Quality fill can help the pillows keep a more consistent shape with regular use. A two-pillow set gives households a matching pair for a consistent sleep setup. Quantities are determined by program allocation, and qualifying stay selections are based on scheduled availability at participating locations. If your household is eligible, shipment will be arranged after the short response form is completed. This notice is intended for guests connected to qualifying stays within the last year and covers one pillow set per household. Thank you for choosing a Marriot Hotel. Your time with us remains important, and this follow-up is part of that recent stay record.

I checked the route you mentioned, and the earlier train seems more practical if everyone is starting from the same area.
It leaves enough time to walk over without needing to rush, and the station cafe is usually open if anyone arrives early.
If weather becomes a factor, we could switch to the indoor location and keep the general plan unchanged.
I am also fine bringing the printed copies so nobody has to rely on charging a laptop midway through the discussion.
Send the headcount when you can, and I will sort out seating in a way that keeps it simple for the group.
