I use allears.net as my go to for menus. They list:
Complimentary Beverages Include: - Yuengling Lager, Budweiser or Bud Light Draft Beer
Concha Y Toro Frontera Chardonnay, or Beso Del Sol Sangria
Coca-Cola, Diet Coke, Sprite, Pink Lemonade, Coffee, Hot or Iced Tea, or Milk
The punch I think you refer to (I had one of these on my last visit) is the Pele's Fire Punch - not sure I would call it a small upcharge though at $15 a drink.
Pele's Fire Punch - The Volcano Goddess' blend of Bacardi rum, Myers' Original Dark Rum, Banana Liqueur, blackberry brandy, pineapple juice, and Grenadine served in an authentic, hand-carved monkey coconut. You keep the coconut! $14.95
