We're going to Disney World in January for 14 days. It's 2 adults and an 8 year old. Right now, we plan on doing 7 days in the Disney parks, trying out an airboat ride and checking out the outlets. I'm looking for 1 or 2 other activities to round out our trip. I'd like to keep them fairly low cost (maybe no more than $20ish/person.) We're pretty open to all experiences as we always like new things and we'll have a rental car, so please help me with suggestions.
