CT is a tough nut to crack for someone on a limited bankroll. Rules are bad and limits are high, that's a killer combination. Also tables often managed to full which means it's not easy to table hop like it used to be. For shoes you need at least 100-125 of your big bets. If you're playing on a $10 game that's $10,000. If you want to play on a smaller bankroll you need to find better games where you can get a bigger edge. PA has surrender. Wendover and Reno NV have old schools 3/2 single deck. Las Vegas has locals casinos with $10 double deck which are great for low limit play. On a bad game you may need 150 top bets to have a legit chance to survive, on a great game you may need only 50-75 top bets to survive the swings. If your bankroll is really small you may just decide to take a shot (Hail Mary approach). If you win you get to keep playing. It's always a judgement call.

CT casinos will fax your photo to each other so a backoff at any one of them should be considered a backoff at all of them. That said, if you're not counting cards you're just gambling anyway and what's the fun in that. MGM Springfield probably does not share outside of their company...especially for new players. They are in deep competition with the tribes right now and aren't going to give them anything.
