According to the Midsommarfest site there is no entrance fee but rather, "The suggested donation for Friday night is only $5." So the Groupon value is actually only up to $24, correct? Buying the Groupon allows one to pay just under $5 per drink instead of $6 per drink, which I believe is the cost of some drinks but perhaps not all.

The Groupon factors in the suggested donation as it reflects the best possible value.
