Actually for us it is
we don't make as big noise as the celebration in USA but we celebrate the day in the island and normally all our stores, malls and the goverment are close even our private sector is close there are only a few "island holidays" that this happen and they are:
* 4 of july
* new years eve
* catholic Friday of our saint week (semana Santa)
not even the private sector industry work during those days Only Old San Juan and our tourist areas near the Cruise ships are mostly open for tourist so I am asking if st Thomas is the same...
