This is the first trip that DS carried a bag in the parks. He actually did really well. He kept track of it, he carried it himself, it worked out great! He had his camera, his cell phone, his coins for pressed penny machines, his poncho, and his badge holder with his park pass and room key. We do NOT allow him to have room charge privileges. I kept his money in the room safe. If he bought something we charged it to the room with my key or DH's key, then I took the money out of his envelope later.
I think we only got a locker 3 or 4 days this trip. In the past we have had a locker every day. I am trying to remember why we used to get a locker. I think it was because of the refillable mugs. We would bring the mugs on the bus in the AM, then rinse them and refill them on the way back to the room in the afternoon. No mugs this trip meant we didn't really need a locker. DH typically did NOT carry a bag, which is why he looked like a drowned rat after that one rainstorm. His shirt was still wet 3 days later. I encouraged him to bring a bag after that, but he didn't.
