I decided to leave a comment about Buster to hopefully help others even though we've used them for corporate events rather than weddings. Over the past 3 years, we've rented 6 times with Buster for either various sized limos and luxury buses (a...ll 6 times we happened to rent in various parts of Texas). Things I love: incredibly easy to book, change times/dates without penalty, and cancel and rebook a different vehicle. Everything can be done from the website after you book and create an account. Response time is quick (for example, Buster usually sends us the exact look of the vehicle with the drivers name and direct number... on the two occasions that the event was approaching and I didn't receive this info, I went on the website and sent a message through that particular booking, and they responded ASAP with the info). The drivers have always been professional, patient and courteous - also willing to go the extra mile (example: we were on South Padre Island and the car was a bit early; I asked him if he could take our guests up and down the island once in the limo just for fun and he was happy to do that. Another example is we were trying to get a very large bus down a narrow road and though I was nervous, the driver was not and was eager and willing to get us where we needed to go and make it easy on guests.) I've never had any trouble with billing, either before or after, and I've never been disappointed in the quality of the vehicle (in fact, I've actually been upgraded for free once).
Helpful info: When booking online, book vehicle to come early to the event rather than on time (i.e., if you need it at 4:30, book it arriving at 4:00). Buster will usually do this anyway, and add the vehicle to arrive 15 minutes early, but I'd still book it coming early and have the driver wait rather than the guests. I highly recommend Buster, mainly based on ease and reliability. Buster has made this aspect of my job much easier! I hope this helps someone!
