Lucky you - ours were wound up.
Just in case yours are more like ours....
We didn't try to nap in the room...at some point they would fall asleep exhausted and we'd let them stay where they were - stroller, bus, boat....whereever. Taking them to the room put them to sleep on the transportation - and ten minutes was too little nap to get them refreshed, but too much nap to get them to sleep again.
We'd lie down with our kids at bedtime, turn out the lights and let them go to sleep. Sometimes took half an hour. Once they were asleep, you can creep out of bed and try sitting on your balcony (if you have one) with a book or use a booklight in the room. We'd also swap trips to the hot tub at this time, I'd lie with the kids in the room and hubby would tub - then when he got back the kids were asleep and I'd go tub. Usually, once our kids fall asleep, they are difficult to wake, so we could talk quietly or read with a booklight. More often, I'd get back from the hot tub to find my husband reading or playing computer games on his laptop, I'd get into jammies and fall asleep.
