We are heading to Philadelphia for Memorial Day weekend. Kids and DH have never been. I used to go all the time when I was kid, but haven't been in over 20 years.

Can anyone recommend a good hotel for a family with 2 kids? We are looking for the following:

1. Safe area
2. Centrally located (so we can walk to most "touristy stuff")
3. Pool would be a plus, but not required

Thanks for any help!
