Travel cot for wriggler

[TheaJess]

I have a standard travel cot but baby doesn’t sleep through the night in it. She’ll have a short nap but, because she moves from one end of her cot to the other at night (several times), the lack of space wakes her up. We’re going on holiday soon and I know that she’s be unsettled through the night. Only 17 months so not old enough for a ready bed or mattress on the floor.
Can you get extra large travel cots? Would that even work because still not as big as her cot bed. I’ve tried an internet search but not sure what to get. Also seen attachments to put on adult bed but I’m not keen on sharing bed with her in case I squash her...
TIA

Have you actually tried a mattress on the floor? My DD is only 1 but she sleeps happily on a floor bed when we stay at my parents' house.

Thanks for your quick reply! No... I haven’t. I’d expect her to crawl off it and explore the room rather than go to sleep!

My DD did for about 10 mins the first night, then fell asleep. The second she just went to sleep straight away! I think weirdly having all the space made her not that bothered about it
