Transportation

Hi! I am looking for transportation to the venue which is 45 min from our Airbnb and then back from the venue to the air bnb. All in all it’s 45 min one way so we wouldn’t be using the transportation for more than 2 hours. All the limo and party bus places charge by hour but for the whole entire time even when you don’t need to be on the bus or limo. Does anyone have any suggestions? We have about 25 people that would need to fit!
