Do I need reservations or tickets in advance for Monday?

It makes the whole process go much smoother if you do, however its technically not necessary.

I would, just to be safe.

Get reservations if possible. 👍

Get reservations to be safe

Last year we went without reservations and it was sold out. This year I made reservations and it was much smoother.

I thought the Gardens closed the end of October expect except for special events . Join us for our winter event, Gardens Aglow November 17-December 31 Thursdays-Sundays from 4-9pm I'm not sure they're open Monday the 11th.

Not essential

I think its better to do reservations
