Do you have any preferred types of activities/sights you wish to see outside the park?  We really enjoy the Pennsylvania Dutch areas to the East of Hershey.  If that appeals to you there will be lots of hotels convenient to both areas.

We stayed at the Best Western and Liked it. Of course, if money was no issue, the Hotel Hershey is amazing.

The Hotel Hershey is amazing and depending on dates/days of the week you can find good deals that include breakfast. The perks are great - free admission to the Hershey Story Museum, the Butterfly House and the Hershey Gardens. We take advantage of the complimentary car service to surrounding attractions.

If you are here over a weekend, the Broad Street Market, the Millworks (restaurant and artist galleries) and Midtown in Harrisburg are worth seeing on a Friday or Saturday.
