CLASS CHALET OR OVERSEAS TRIP WITH RELATIVES ?!

argh both dates clashed and i thought it wont
now i can only choose one out of the two .
i want to go for 2 D:

Class Chalet might be the last time i can spent my time with the class because this is our last year but i haven been on a overseas trip with family and relatives for a long time already .
Furthermore, we are going hong kong this time round && its the first time we are going so far in such a big group .

If you are in my position , which would you choose help me !

Ps: im really really really dissapointed with my results
except for a&e maths .
