We just came back from Acadia and Schoodic Woods Campground.... That campground is just beautiful.
Loop B has water/electricy, and Loop A has electricity only. That being said, the bathrooms are nice (Everything is new).....but there are NO SHOWERS on the campground.
Sites are huge and super clean with a picnic table and a big fire pit.
Schoodic campground is 5 minutes from Winter Harbor. Quaint little town (not too many stores) but still has an IGA, Ice Cream place and a few restaurants. The Raven's Nest is a very good restaurant (A little pricey, but the food was great).
Take a ride to Schoodic Point....you won't regret it. Bring your folding chairs or sit on the rocks and enjoy the views.
If you plan to go to Bar Harbor (a little less than an hour away) you have three choices:
1- Take your car (good luck finding parking)
2- The shuttle bus from the campground (no cost....it's free)
3- Take a ferry from Winter Harbor ($24.00 return each adult)...45 minutes.
As for Acadia NP on Mt Desert Island......your car or the shuttle.
I forgot to mention: The shuttle will accommodate your bikes.
I may have forgotten something.......but anyway, here is link to a few pics
