Thanks everyone. We've decided to stay put off site.
Yes, I know it's best to get there early...but we have 7 day hoppers, we're older, like to take our time, so if we only go on a few rides each day we plan on going back to each park 2-3 times. We've been to the parks before and know what we want to see or not bother with.
Plus, we live on the West Coast so it takes us several days to get used to the time change - I don't want to rush to get anywhere for an 8 am opening when it is really 5 am on my body - that's not fun or a vacation.
I've also found some other threads which give short cut driving directions from where we are, and they are great.
