Well...hubby and I were seriously considering cancelling our trip in January

I know.... Well we have a lot coming up next year including an anniversary trip to Hawaii, a wedding in Texas..bla bla bla
So my husband was trying to cut the disney budget. So we decided to forgo the train cost of 960$...and DRIVE

I am a little reluctant about this to say the least.
Here is the plan....
Leave on Jan 3rd 7am and drive 11 hours-ish to Hilton Head an stay at the disney property there on points (no money spent)
Leave early the next morning and drive the rest of the 5-ish hours to disney.
Enjoy our 5 days at AKV 1BR
Drive to Hilton Head and spend 2 nights.(also with our DVC points)
Drive home on the 10th.
His mom is giving us $500 for christmas so there are our park tickets paid for.
Website says cost to drive is 110 each way including tolls.
We will have a full kitchen so we can have breakfast and maybe 2 dinners in.
Would you guys do this??? or would you rather just cancel? Advice please.
