Blisters can be a big problem. We had blistered feet so bad we could barely walk by the time the week was over. I would tell them to get some good shoes and to grease the bottom of their feet to prevent friction. We had blisters starting by the end of the first day in the parks.
Wanted to add, I do not stand more than 60 minutes for an attraction. I refuse. I cannot do that, if I did that, it would ruin my day. I utilize FP for longest wait attractions
NON cotton socks! And some feet are more persnickety than others, so the brand and exact "fabric" of the sock can make a difference. Yes to good shoes (though the definition of that is different for every foot...I myself LOVE a Crocs flipflop in the parks, while that would destroy another person's day), yes to bodyglide or baby gold bond goop or even vaseline. But a good SOCK is also an important foundation, if wearing non-flipflops.
mute point
One person had to go to the bathroom, a couple would stand outside and the rest would wander off to look at something. By the time the first person was washing their hands, inevitably someone else had to use the bathroom or "might as well try".
Any hints or stories I can tell them that will get them motivated?
