We are looking to visit Boston for 1-2 nights sometime this summer with our 2 kids, ages 3 and 5. We were looking at August but it is hard to find anything reasonable. We wanted to stay at the Marriott Long Wharf or the Seaport, however the prices are crazy high! The Seaport from Aug 18-20 was $590. We are willing to spend maximum $250 per night. The main purpose of our visit is for the Children's Museum, but we were also looking into the Aquarium and/or the Science Center. I've been surprised to see how quickly this is all adding up. The hotels charge $40 for parking per day! Hopefully someone will have some suggestions as to where we can stay or this might just become a day trip. Any tips or helpful ideas would be greatly appreciated. Thanks so much!
