Best transportation option for group of 8

[ms.yt]

I need an airport pickup/dropoff in November for a group of 8 people. We are staying at the Dolphin. I looked on Yelp and saw several other options besides Mears, which I've not heard great things about. We'd like to get with a van or limo (if they weren't too expensive) that we wouldn't have to share a ride with someone. Does anyone want to share their experiences with area transportation services other than Mears?
