When I checked their website, it seemed like you were on the tour the entire time--i.e. you travel with the same 20(?) or so people, stopping at each vineyard for a set amount of time, and then (depending on the tour) stop for lunch as well. Is this accurate? Is there any shuttle/ trolley/ wagon/ whatever that just goes between the different wineries every so often and allows people to get on/off whenever they are through at a particular vineyard? A friend of mine mentioned a shuttle between the vineyards that we could take, but I dont know if she was referring to something like grapeline, or something that was more akin to just a regular shuttle.
Also, where are the pickup points for grapeline? We will probably be staying at Pechanga, maybe Pala. Is there a pickup point there?
