Taxi, Shuttle, Bus? Any suggestions? I'll be traveling with my husband and my parents.
Becky - According to www.edinburgh-airport-guide.co.uk/transport.html
Edinburgh Airport by Bus There are several regular bus services between Edinburgh airport and the city centre. The bus stands can be found in the front of the terminal building outside the UK arrivals lounge.
The number 100 bus is a regular shuttle which runs between the airport and the city (close to the bus and train stations and the high street.) This service runs 24 hours a day, 7 days a week, every ten minutes during peak hours and every half an hour off-peak.
In addition to the info posted above, here's another link that has info on transportation from Edinburgh Airport (scroll down and you'll see the info relevant to your question)

i was in Edinburgh a couple of weeks ago and took this shuttle to the airport. it was very convenient since it picked up just a block from our hotel and right in front of the Waverly train station. It's a blue double decker coach and costs 3.5 GBP each. we only flew out of Edinburgh not in, but i assume it picks up as regularly as it drops people off.
Thank you all very much for your help!
