This movie is from the 90's. It might have been on disney channel. It's about a kid who goes back in time to medieval times. The only parts I remember are him and some people hiding in a trap door in a house and someone covers it with hay to hide them because their village is getting attacked. The other part I remember is when he goes home, everyone is outside having a party or putting on a play or something like that. I really hope someone can help me. It's been driving me crazy trying to find it.

Either A Kid in King Arthur's Court or A Connecticut Yankee in King Arthur's court. 2 movies same basic story

Could also be Willow. Kind of off the wall, but there is the scene where they hide under the floor in the little village. And I don't quite recall if the end was similar to a "party", but the beginning definitely was.

I was thinking Kid in King Aurthur's Court as well.
