Agree with everything that has been said here. Be warned though that once you turn left....you never turn right again !!!!
My missus and I first flew Virgin n 2006 when we both retired. We had always wanted to spend a week in DC to explore and see all the famous sites. We first used PE and enjoyed it but always looked enviously to the pointy end when we first boarded.
The next year we flew into Boston for a week and again used PE. In 2008 we decided to tour Maine,Vermont and New Hampshire for a 3 week tour. And for the first time ,we took advantage of the Virgin sale and flew UC.....and we were hooked.
We now return each Autumn to spend a week in the northern woods of Northern Maine up near Moosehead Lake, a week in the Catskills and our final week in Wellfleet on Cape Cod ( our particular favourite ) And since 2008 we have always used UC
We are off again for in October for our fourteenth trip to the US with Virgin and in UC. Being old pensioners now, we could not afford the "real " price of UC and always take advantage of the sale that generally appears on the website in early Spring.
So enjoy your first time in UC. We know you will and will probably be hooked like most people here. It really is a wonderful product. Especially the drive through at Heathrow and the truly wonderful Clubhouse
