Here's my 2 cents. SInce you are selecting on Tuesday, it would appear you will be arriving on a Saturday. That being said, don't be too surprised if you have some initial difficulty due to the system being bogged for a Saturday arrival. But, keep persistent and patient. Last Tuesday was my date to select, and for about 45 minutes at opening, the system was not working well at all. It was frustrating, but I was able to get everything except for SDD. But admittedly, I wasn't trying to get that particular one and expect to rope drop it on the day we go to HS. Every other FP we wanted was found and adjusted accordingly. Point being, be persistent and patient. All should be well. AND...don't be late to begin your selections, with a plan in place. Good luck!
