They are mostly busy from 6-8pm But you should be good if you go around that time
I think you'll be ok. There's ample seating and it's NEVER been crowded when I've gone. There should be plenty of room for your party of up to 7.
It should be good
Whenever and gone has enough space for group. Since in my case we are 8 and we have never stayed without sitting
I've been to Marco's many times throughout the day and have never had any problem with seating. This includes parties of up to sizes of 10. I think you will be fine.
