I'm planning a bachelorette party soon and have found some good options, but most of them are pretty expensive. I was wondering if anyone knows of a party bus/limo rental service that is reasonably priced? I only have 8-9 people (hence the high price per person).
I was wondering if there is anything around $100/hour?

There are often sections on company websites called "hen party limo hire", where you can find promotions for bachelorette parties. Try looking for packages for a couple of hours, it will be more profitable than taking a long tour around the city.

Choosing transport for a large group is always hard, mainly whilst you need each consolation and price range. Prices are regularly better than predicted, but there are offerings like limo hire London that offer decent and less expensive service. Their delivery creates a groovy atmosphere, and the driver cares approximately your safety and peace of thoughts. Before booking, I recommend you to clarify what precisely is blanketed within the price.
