If your invitation says “and Guest,” then yes, if not, we would prefer if it was just you.
Cocktail, please. But we want you to feel comfortable, so if those shoes are too high or that top button is too tight, let it all hang loose. But no jeans, please.
Powel House is a 0.5 mile walk down 4th St from the Wyndham Philadelphia Historic District.
TLDR: The cost will out-weight the benefit. The Philadelphia International Airport is 11 miles from the Wyndham Hotel in Old City. Otherwise, the city is very walkable and public transit is easy to navigate.
