We've not gone through yet. Most likely we'll transit early next year. We took a couple vacation days and went to Panama City, then to the Canal Museum at Miraflores Lock. Extremely worth while. The restaurant there (pricey by Panama standards $25 / person) was excellent and we ate on the overlook where we could almost pass food to the ships bridge as they passed by. Cool. This picture is looking N from the locks towards the Caribbean.
