PTing and long outings: WWYD?

We started PTing DS2 10 days ago. It's going pretty well, but he still has accidents. He does well at home, especially when he's bottomless and well at daycare with consistent reminders. We were away last weekend visiting family and for convenience, used pull ups when we were out of the house for long periods of time. He used the public restrooms at least once per day, but also peed in his pull up. Once we were home, he was back on track and he has been doing great this week at daycare.

We are going away again and will be at Sesame Place, Please Touch Museum, Dutch Wonderland and Hershey. Part of me doesn't want to deal with accidents at the amusement parks or running to the bathroom every 30 minutes. DS also has a tendency to say he has to go, gets to the potty and declares he doesn't have to go, throws a fit if I try to keep him on the potty, does this a few times and then he ends up going several minutes later. At home, there are times when he'll also run to the potty a few times before actually going. At the same time, I don't want to mess up any progress we've had with PTing.

Does he have his own potty? Bring it with you and put it in the stroller

Re: PTing and long outings: WWYD?

We just bought a travel potty in addition to the baby bjorn little potty.

Do you just use the travel potty in case there's a long line in the bathroom? I don't think I've ever noticed anyone use a travel potty in public except in the back of a minivan or SUV.

I think it may be easiest to put him in a pull up, but take him frequently to the potty. I don't want to mess up all of the progress he has made, but I also don't want to spend every 30 minutes in an amusement park running to the bathroom.
