Replying to Concussion advice

This past Wednesday ( january 13) i french fried when i should pizzaed and ended up bangin my head a bit on the snow after catching my tips trying a nollie of a roller...

i ended up having a bit of slurred speech that evening and was a bit nautious and dizzy, doctor said i had a concussion, i have been taking it super easy for the past few days with no physical and mental activity. I feel 100%

the catch is,in one week i have a ski trip out to colorado skiing January 21, 22, and 23. I will be flying out. I paid a bunch of money for it and i really really want to go but my parents dont want me to.

My question is,- is it a bad idea to go, and if so why?
