Actually it sounds like you have the best scenario. You have a month in which to either do it all at once or slowly bring things over. Who cares if hubby is in denial. It means you'll have to take the lead in packing, which is ideal. You can be sure to go through exactly what you need or don't need.
I've moved so many times, it's old hat to me. My recommendation is that you start with the non-essentials first. Pack up pictures, books, videos, holiday stuff, dishes that you only use on special occasions.
Then map out a plan to pack one room at a time. It'll keep you on track.
And look for opportunities to get rid of stuff. That's the one part of moving that I love. Yard sale! The perfect time of year to get rid of stuff you don't need. The last thing you want is to pack stuff that you do not want or need anymore.
There's so many websites out there dedicated to providing tips for moving. I've moved on my own, with a moving company, without a moving company, across states, across mere blocks, etc. It seems daunting, but once you map out a plan and tackle it a piece at a time, the easier it becomes. And unpacking becomes a breeze if you pack smartly to begin with.
Anyway, I linked one of the many sites you can go to for ideas.
