No answering machines at this business, and I'll give them an A+ for that. She answered on the first ring -- I hate to call people so early in the morning but this woman was right on top of things! On short notice, I had to get up to the airport and it was 5 AM. No problem! They sent a driver within 30 minutes. He was very pleasant and so was the ride up in a nice lincoln. I'd use their service again! Five stars for Emerald! Thanks so very much!
