I wanted to add that there are several forms/types of Vipassana and several different types of centers that conduct retreats. Many people get confused and think that there is only one type of Vipassana.
The Insight Meditation Society (IMS) is located near Boston and is the most extensive center in the US.
“IMS offers Buddhist meditation retreats at two facilities – the Retreat Center and The Forest Refuge – in rural central Massachusetts. The Retreat Center is one of the two IMS centers in the United States. However, all Buddhist centers teach vipassana/vispashyana.
It offers a full yearly schedule of more than 25 meditation courses, ranging in duration from a weekend to three months. Most retreats run for 7–9 days.”
Insight Meditation Society (IMS) uses a sliding scale to charge for its retreats and I have found them to be my favorite center for going on a retreat.
I came here to second this. The author clearly has experience only with Goenka and has absorbed their atypical use of the Pali word "vipassana". It's not usually used as a noun to describe a retreat. Nor was it "lost" for centuries. Most serious Theravadan retreat centers have been doing plenty of vipassana.
IMS is a wonderful facility. On the west coast, its sister center is Spirit Rock, though they're not quite as well set up for long retreats.
