We are planning a trip in June 2013 or over the 4th. We were going for 3 days but when reading forums not sure if that is too long. Would love peoples opinions if there is enough activities/things to see to be there 3 nights or if we should do something else. We are coming from TX and it is not cheap so want to stay but don't want my husband bored if we are "people watching" 50% of the time. Your thoughts?
