re: Disney Pros, is it worth it to stay on site?

Most breakfast buffets are $26/person. And the a la cart ones aren’t much cheaper. Not saying your plan doesn’t “work”. But no reason to exaggerate how much you’re saving. I’m also sure you get free vallet parking if you have a meal in the parks. Good for all day. So you’ve been missing out on that by this “workaround” of eating at resorts, and transportation to and from them when you could have been parking vallet for free, taking the monorail to MK, eating breakfast there before the park opens, and already be inside without having to deal with the heavy traffic at the entrance at all...

So, congrats on doing it wrong I guess.

ETA: Just looked it up. You can vallet for free anymore (ended about 2 years ago) unless you have a Tables in Wonderland card, which I believe you are eligible for as a Florida resident.
