My husband and I stayed at Aisling in August 2008 with our 2 year old son. He loved walking down to the water to watch the ducks, running around in the back yard, and playing with the toys in the house. We'd recommend (for any kind of travel) to take a "white noise" travel clock to help infants sleep sound. The property was very clean; I appreciated the newer model of coffee maker. The owners provided books and pamphlets with restaurant reviews and information about the area.
I'd definitely recommend this cottage to friends-- even those with one or two young children.
It might not be up still, but on our way to Bass Harbor-- coming from Southwest Harbor-- there's a handwritten sign that says "GIANT CHOCOLATE CHIP COOKIES". We followed the sign to a house, and this woman sold us the most delicious cookies known to man or woman. I think Sawyer's Market in SW Harbor carries her cookies too. Also, A & B Naturals in Bar Harbor has an incredible selection of food and natural medicine (if needed) considering the size of the store. Also in Bar Harbor: the Bagel Factory! It's hidden, but if you can get there early, it's worth it.
We really had an incredible time; we'd love to go back and stay at Aisling again. Thank you to the owners for all of the extra amenities.
