Did you pay the 432 dollar extortion fee and if not what was your secret to getting a ball at Cooper. The only way I have successfully booked a ball at Cooper was when I was home with fiber optic cable booking for a friend.
My success rate has been about 80%.
No payment for advanced access. My success rate when trying to use BB is primarily due to being logged in and selecting a ball (not necessarily the "best" ball) AND being out of sync with the typical weekend start of charter.
And only way I have booked is while on boat via TMM Charters FREE onboard wiFi.
