I have researched threads regarding traveling while on IP. I will be attending a conference in Long Beach, CA; and then vacationing there (staying at Disneyland's Paradise Pier Hotel, Catalina Island & etc) for a total of 7 days.
From what I've read on the traveling threads, I can take the IP packets in my carry on, any premixed should be put in Ziplocks

and placed in my checked luggage. I'm fine with all of that.
What about the veggies? I'm really concerned that the conference won't have the restricted veggies that I need, in the past it has not. I think I'll be fine in the evenings getting to eat out at restaurants. Has anyone packed cut up veggies (cucumbers, celery) and taken them on a plane? If so, how did you pack them...ie checked bag or carryon? Am I just overthinking this?
While in CA I don't want to drag my family around to grocery stores...I'm not sure I'll have much time to go shopping those 1st few days while attending the conference. I've searched Disneyland eating posts & discovered that there's not a lot of healthy choices...kind of surprising since the place should promote healthy eating to our children!! If anyone has vacationed there with success, please let me know how you handled that as well.
I apologize for the long post..Thanks for any advice you can give!
