We were in HHI at the beginning of March this year. The day we checked in was pretty cool. Maybe 70. But the next day it was in the 80's. We drove from NJ to HHI and then from HHI to WDW. The drive takes about 6 hours. It's a straight run, it's very bearable actually. On our return to HHI from WDW (which was about 8 days later) the weather was beautiful, and warm.
