holiday post cycle?

could do with some good advice please.  been asked if i'd like to join my family on a weeks holiday somewhere sunny but we would travel 10days after i finish my 8week x-mass cycle.

what is the best thing to do, either cut cycle short by 2weeks and get at least 3weeks pct under my belt or extend the cycle further and hit a 10 1/2 week cycle?

i just don't want to lose the strength gains i've made as we won't be going anywhere with a gym.  if i kept on then i'd at least be able to maintain via elevated test and bodyweight exercises & i wouldn't have to worry about taking all my pct supps with me.

is greed outweighing common sense?  if anyone who knows more about this than me could offer their opinion it'd be much appreciated.

ta, rokks

(if i do make this my last week i could increase xmass dose, add a weeks sd and really hammer it in the gym every day... would 3weeks pct be long enough to cement my hard work?)
