We ended up hiring Coastal Livery Transportation Services less than two weeks before our wedding, after realizing that carpooling with our bridal party to and from the church was n...ot very chic or practical (haha). Thankfully because our wedding was on a Sunday, Coastal Livery had availability. Their price was comparable to a few other limo services I called, and their reviews were consistently strong.
On the day of the wedding, our driver arrived 30 minutes early to our hotel to make the first trip with the groom and groomsmen (which was great and so much better than being late). When my fiance told him that they weren't ready yet, he said "no problem whatsoever" - he would be waiting outside and ready when they were. After taking the guys to the church, he returned to the hotel right on schedule to pick up me, my parents, and bridesmaids.
While our driver was completely professional and drove well to and from the church, he was a bit on the serious side (thus the 4 stars instead of 5) and didn't offer any friendly conversation or congratulations. The limo itself was clean and well stocked, but keep in mind that it is a very tight fit for 14 people. On the way back from the church when we had both the groomsmen and bridesmaids together, a few groomsmen ended up riding with their wives because they didn't want to squish into the limo. (I'm not saying it wouldn't have been possible, just probably uncomfortable.)
