The foam bed idea will probably not work out considering she's never slept in it before. It might cause too much excitement due to the novelty and cause for her to get overstimulated, which will result in not such a great night for you both. My daughter, my husband and I stayed at a hotel when we went for vacation to Disneyland last year. She was 20 months old and we asked the hotel for a crib. In the end she didn't want to sleep in the crib. We put her in bed with us (between us two), which is something we had done at home from time to time. We slept like that for 3 nights and it was very successful. Just made sure low light was on an hour or so before bed so she wouldn't get too overstimulated. She was also able to take naps on the bed during the day while daddy and I hung out on the balcony within ear shot...good luck :)

I have spent MANY nights in hotels with our daughter. She is three now but it started when she was about six months. A night here for a wedding in another town, a night there for a funeral. Family vacations and so on.

We have done both ways of sleeping. Her in our bed and her in her own. My daughter has never fallen out of bed though, so that wasn't our worry. I found when she got her own bed it was waaaay better for me lol. I've never slept well with her in the bed with us. But it has worked both ways.

Of course, the excitement of a hotel throws the sleeping schedule out the window...but every now and then that's okay.

I bought a fold up travel cot from walmart. Folds up like a camping chair and our son had no issues with it. He was prob a little over
2 when we used it.

While my son doesn't share a bed very well at home, I've discovered that sharing at hotels and on vacation is the best way to go. If possible, I will even push the bed up against the wall (they're usually really close to the wall, anyway), or line an end with pillows. He's never fallen off, though. Because it's a new, unfamiliar place, he's more than happy to snuggle up against me and fall asleep. And yes, you'll be able to sleep, too. Bedtime sort of goes out the window and they just stay up for as long as you stay awake, but once you start to fall asleep, they get the idea. Best of luck!

We tried just bringing the mattress when we stayed overnight. Big mistake. When we said go to bed, he said that it wasn't his bed.
Next time, we probably will bring his toddler bed even though it takes lots of space.

We ended up sleeping all together... and SLEPT! It was actually rather sweet. Though my husband had to go to bed at 9:30 - he's a late nighter! Me I was whopped so I didn't mind going to sleep early - I usually do... 2 year old saps my energy! And there was no trouble going back to the toddler bed when we came back!

Thanks for all the good advice!
