Christmas holiday ideas 2015

Hi Im's,
For as long as I can remember (well ok the past 7 years) I have felt worn out after Christmas holidays of 3 weeks, I actually look forward to coming back to work part time just for a break!
Hubby and I have 4 boys 10, 7, 3.5 & 2 and I'm wanting to layby or save for a holiday that will bring some relaxation instead of the constant food shopping/cooking/laundry/taxi-ing/packing cars/unpacking cars etc.
I was thinking a cruise (which for all 6 of us is expensive im thinking? )
Love to hear suggestions from others on some awesome ideas for a relaxing Christmas getaway.
Thanks x
