In the following escape rooms in Jackson (MS), you must purchase the entire experience at once. You'll only play with the members of your own team and won't be paired with strangers.
The only requirement is to meet the minimum number of players for the room — the price is usually set for the room itself, though it can also depend on the number of players.

As you learn the secrets held within the cabin, you realize you may be in more danger than you were before.
Can you infiltrate Luigi's restaurant and retrieve the stolen recipe or will you be sleeping with the fishes?
Can you navigate the ancient mysteries of this Mayan wonder and find the priceless artifact or will you succumb to the Temple's ancient curse and get trapped forever?
Escape is the only way to salvage your life and prove our innocence.
Can you bring this mafia laundering scheme down or will you be hung out to dry?
