it sounds like it may be too late to be of use, but i should say that we got married in the summer of 2001 at Awbury Arboretum in Germantown, which was a wonderful place which had a lot in common with Bartram's but which we preferred, mostly for intangible reasons. We also used Shackamaxxon catering, and were very very happy with the choice. They were much better at customizing and working with us than a lot of other places seemed to be, and had great food at relatively cheap prices!
