Vigilent check your PM's
I am on the whole not sugesting that you should not go to the USA but your posts seem to indicate that you have been given rose tinted glasses for viewing the situation.
The idea of making you do all these hours is for you to learn a bit about flying and more important for you is to be able to retain this knowlage and to be able to draw apon it when things are getting tough and the pressure is on, for instence on your CPL/IR training.
Bashing 100 hours out in one go in the wide open spaces of Texas will not help you for the CPL/IR in EASAland because people simply don't retain much from such intensive flying, this will result in extra training costs at "approves training rates". this is a cost that will only become apparent long after the Texas hoilday in a distant memory.
Far better to go to the USA and do about 50 hours and then return and do the rest of your hour building in Europe just before the CPL/IR course, this way you will be up to speed in the enviroment that you will be tested in.
The Hubb city opperation looks from the website to be one of the better places and if you have a personal recomendation all the better but I guess that the person doing the recomendation is only just ahead of you in flying terms, I have seen this all before and after thirty years and 10,000 hours in the business the old Arab proverbe "Cheap is not so cheap" rings as true today as it did when I started in aviation.
Good luck with your flying but take care who you chose to advise you, bad advice seldom comes cheap!
