I had a PM and I thought I'd share the answer.
May 31st, Saturday, will be the day everyone needs to fly into Miami or Fort Lauderdale, to make their way down to the Keys. Or of course you can drive down.
The earlier you get in, the better.
Walter will plan on starting the pool work, and book work, that day. Again as soon as everyone is in, he will want to start.
No later then 6PM for this. 5PM is better.
Sunday, Monday, and Tuesday, will be the dives needed for Wreck Certification to be earned.
Hope that helped.
Walter, of course feel free to add anything I missed.
