Every time I called U-Pack, there was a really friendly, helpful person on the other end. They helped me to estimate just how much space I'd need to move all of our belongings and they were right on! When I first tried to figure it out on my own, I had estimated that I'd need one and a half 28 foot trailers. I was wrong. They helped me to figure out that I'd only need 24-28 feet and that's exactly what I used. They know what they're talking about!
All our belongings made it from Illinois to Florida unscathed. The price was reasonable. The folks at U-Pack were very helpful. I was absolutely pleased and if I ever move again (Oh God, please no), I'll use U-Pack again.
Here's little video of our move that I made. :)
