Per groupon fine print listing: "Magnolia policy maintains that a guest can return free of charge (with proof of receipt) within 24 hours after the initial visit." Since there are nothing on their main site and some here say 7 days are valid, I would also recommend calling to double check.
Yes you can go back as long as it's within the 7 days
Yes
Admission is currently on sale on Groupon
No, only for the day. The admissions price is $22. To access Mainhouse, nature tour, cabins, etc is $8. Each in addition to the $22
Idk if you like give them a call
