Whatever you do/say, try not to make him feel guilty or blame him, I'm sure he already feels bad enough about it as it is. Sorry if that wasn't your intention but your tone in your first post came off as sounding like it was his fault and you wouldn't put up with it.
I agree. I was quite saddened by the original post because, to me, it also came off sounding like she's annoyed with him.
schrodstrip,
I *do* understand that you don't want a wet mattress on your vacation. I know the problem all too well but please try to be sensitive to your nephew's feelings - his feelings are *way* more important than any mattress or blankets. My eldest son was 11 last Sunday and he still wets the bed every single night. We use waterproof sheets *and* disposable sheets too while we're on holiday. The waterproof sheets can be purchased at any major department store. The disposable waterproof sheets are a Pampers product. They are available here and, presumably in the U.S. too. You get about 8 of them in a pack - they measure about 2 foot squared and can be placed in the centre of the bed. They can't be relied upon on their own because there's always the chance that they'll get moved around during the night - that's why we use the cloth waterproof sheets too. When they work, it saves us washing his sheet that night. We actually bring our own sheets and sleeping bags on holiday for our son so as soon as we get to the room, I strip the hotel bed clothes and use our own stuff.
Please ensure that you don't make him feel bad about this. He absolutely cannot help it and will need a great deal of reassurance and TLC. I can guarantee you that he is already *painfully* aware of what a nuisance this problem is and I am sure his life has been impacted many times up to now (e.g. sleepovers in friends' houses, camping trips etc.). I find it very helpful to have my son look after his own bed clothes because it cuts down on his discomfort with the problem. Every morning he strips his bed, puts the bed clothes in the wash, grabs his towels and goes and has a shower, first thing.
Also, be sure to bring some kind of scent - perhaps even some scented oils - and open the windows first thing each morning. The scent of urine in the room might be very strong and, of course, unpleasant for all of you and will add to his embarrassment.
It is a very delicate area and can shatter a child's confidence if not handled with sensitivity and care.
EDITED TO ADD: Please don't go down the road of using the dry-nites unless he already wears them every night. They are HUMILIATION in a fancy packet. We gave up on those when my son was 6 and started crying one night because he "felt like a baby". I could have kicked myself. Never again.
Anyway, she said she would talk to him, but I'm thinking she might not. Any suggestions would be wonderful. 
. He does not wet the bed that often but we didn't want to take any chances. We called housekeeping and asked if they had a plastic liner for the bed. They didn't but in ten min. Housekeeping was at out door with a brand new shower curtain liner to put on the bed and a set of extra sheets ... just case 
. In the 15 days we were there he only had 1 wet night 
. We put the wet sheets in the plastic laundry bag that they leave in the room and left a note on it and a big TIP!! LOL When we got back to our room that evening there was a sm. stuffed pluto on our sons bed with a note saying " Sweet Dreams".
