Our 5 day PH at DL plus food and souveniers has maxed out our budget. We have 3 days not at the park to find something fun and inexpensive to do. Is there any fun to be had for nearly free? (Or say abouts the area of $20 for a family of 5) We plan on one day at the beach. Anything else? How's the Santa Monica Pier Aquarium? Worth the drive from Anaheim? Thanks in advance for any and all suggestions!
