Go to a dollar store and buy up a load of little toys and fluffy or shiny or sparkly things. It doesn't really matter what they are--they just have to be something new to explore and play with. (We used to travel with a bag of such items back when we did a fair number of long-haul flights to the UK with our daughter.) Crayons and paper are always a good idea, and there is a little table in the room perfect for scribbling. Favorite snacks that don't need refrigeration are a must--for grownups, too! Playdo might be good--though I think our daughter didn't really get into its squishy possibilities till closer to 2--but every kid is different. How about some balloons to blow up and bat around the bedroom? A jar of bubble fluid that she can squeal over as you blow them so that she can pop bubbles to her heart's content. Books to be read to her, over and over and over...and of course, her favorite lovey--whether it's a stuffed animal or a blanket, it will be a comfort in an unfamiliar place. Keep in mind there will not be wifi or cellphone coverage for long stretches, so if you plan to use an internet device to amuse her, you'll need to download what you want in advance of the trip. You can build a 'tent' in the room by putting down the top bunk and draping a blanket down from the top bunk to the bottom bunk. Probably only one grownup could fit inside with your little one, but that's what the armchair is for! Also, that would be a great activity to bridge into naptime, when maybe a storybook being read will help ease her into a nap for a bit inside the 'tent.'
