That is the week we went this year! Last year we went the second week of June, and found it to be much less crowded than the third week. That said, it wasn’t really that bad. We are always able to find at least a few lounge chairs. No long lines for quick service, but the lines for characters were long enough that we didn’t bother standing in any of them. Last year, you could sort of stumble upon them and take a quick picture and have a nice interaction, but this year the lines gave them away and were a deterrent. Though it was a bit crowded on the beach too, we would still visit this week again in the future. Earlier may be better if you can swing it.
