Best bed rail or bumper for travel?

We are going to our family’s house 8 hours away for Christmas. Our 2.5 year old is still in her crib at home.. she also sleeps in a pack and play at my moms when we she watches her. She is getting too big for the pack and play and feel she would be more comfortable in a bed. Our family has a twin bed that she would be sleeping in. What’s the best bed rail or bumper?? There are so many out there!! Thanks!
