Is it worth it to buy on of those meal deals online? Do any of you keep a cooler of food and drinks in the car and head out to the parking lot for lunch? What are the options. I imagine the park food is sub-standard at a high price! I'll keep a water bottle on me and fill up at water fountains. THat's possible, right? I'll be there on a Friday or Saturday if that makes a difference.Thanks for any opinions, especially from you vets!!
