I have returned from our trip and we had fun. It was definitely different than what we originally planned but that was to be expected. Rides going down, kiddo choosing to sleep in late our first day since we were exhausted and I had no idea that Orange County kids had the day off school until I overheard someone say it when waiting for the bus, so we went when they had a 3 day weekend. We didn't really have a choice in dates since we were going for my son's birthday which happened to be that same Monday. It explained a few things though.
It was crowded but not so crowded you couldn't move. However, most of my vacations are in July so this seemed normal to me. I just felt bad that I am such the clueless tourist that I know I walked right behind some Photopass photographers because frankly, I just didn't see them there until I had already done it (there were a lot out, so it would have been hard to avoid it 100%).
I will be doing a trip report with all the nitty gritty but I will say I definitely like my 7 day vacations vs. this cram everything in 3-4 days version better.
