Hi Kimberly,
With your trip just days away, I'd recommend taking a look at www.touringplans.com; it is a website that offers over 100 itineraries to help you make the most of your days by highlighting the must-sees and what order to see the attractions. While it does have a minimal charge, I think it is a worthwhile investment.
Do you have your tickets to MNSSHP yet? If not, it may be something you'd want to purchase beforehand to save money. If you click
here, you can see the dates, prices, and online ordering link.
The current weather forecast has the highs around 80 degrees and lows around 66 degrees; the exception is October 20, 2011, when the high is forecasted to be 70 degrees with a low of 56 degrees, so you may want to pack a light jacket.
Have a magical trip with many new memories!
