Family trips with significant other

If you were going on a trip with your family, and it’s just your mom, dad, you, and your significant other, would they let you sleep together in the same bed? I am 19 and my boyfriend is 21 and we’ve been dating a year. We got a 2 bedroom, 2 bathroom cabin, and we assumed we would get our own bed and bathroom. We were really excited about this trip to finally be able to sleep together in bed and be able to snuggle, but now I don’t know if my parents will let us😞 so, do your parents let you sleep with your significant other, *on vacation atleast* especially at an older age like 19 & 21?
