Our pontoon rental prices were set on January of 2022. This includes a full tank of gas for free. However, due to the current political climate and what's happening in Ukraine, it's expected gas prices to increase. If gas prices go up, we will charge a gas surcharge at the end of the day based on the difference in gas prices that day as compared to the prices of gas on January of 2022. We are sorry for inconvenience, but it's the current nature of the political climate. Thanks for renting with 30a Pontoon Rental.
