Thats a bit harsh sayin you would not use Mears even if it was free. I also dont think that the drivers are rude in all the times we have used Mears services. And i wouldnt say that the shuttle vans are that dirty. I dont have a bad word to say about Mears. When we arrive in Orlando we have been up usually for about 20 hours and want to get to the resort. We have never had a prob at MCO and i also dont mind stopping at other places, as long as its in WDW, for the simple reason that its been a long day and its been a year since we were last at WDW and at last im here and dont care, just time to relax.
One other small point. Mears is a shuttle bus service and it is not advertised as being a personalized service, Mears does tho provide a Town Car service and a limo service for those wanting a more personal service.
Again just my opinion and i dont mean to have a go at others cos i respect what u all say as everyone will have a different experience.
