So this is a 2 part answer because of that particular week you are selecting (Easter a world wide holiday).
1.
YES many charter boats will allow RB's with advanced notice at booking through out the entire year
IF that boat trip is compatible that day (ie it's an advanced trip). Boats that I know who will {sometimes} run RB trips are Jupiter Dive Center, PuraVida, Calypso, Ocean Quest>Sunny Sunday, Walkers, Salty Divers, and others. The key is to call a month in advance so they can put out the word to their other local RB divers who may be able to jump on the boat since your run times will be different from the other divers on the boat. Also both JDC and PV usually stock Sorb-but again, call in advance.
2.
EASTER Your timeframe is the number 1 busiest week of the year for tourist vacation divers> those 2 weeks of Easter. They will fill the boat and their depths and runtimes will be
HALF of a typical RB's profile. So from a captain's view of trying to track 15 drifting divers on very different runtimes is a big problem for him. How many vacation divers? The boats will be sold out weeks in advance. So much so that a charter many say No RB's, No Scooters, No Guns. Being a spearo, I will be told No Spearing during easter weeks because they are so busy with vacation divers. The other factor/problem with those weeks is boat traffic. It's a huge boat rental week & once a year Budwieser fishing captains with no fishing spots and think we are diving something great to throw a hook on to. They don't look for dive flags and they'll run full speed right thru a group of SMB's with their boat on auto-pilot and your charter captain can't block & protect widely separated divers.
BUT, if there are 4 very qualified RB divers that promise to stick & drift together, that captain most likely will say YES if he agrees in advance with your dive plan (ie 50mins at 95'-100'). During the vacation Easter weeks boat's don't usually run the 130ft deep ledge. Mostly vacation divers will be doing 80ft dives on nitrox to see the fish & colorful reefs and the surface distance between 80ft and 95ft reefs is much greater than the 300 ft separate drops that the boat is allowed to do.
PS> I love diving with RB divers!. We want to go to the same places & depths. Alot of times the RB diver's I'm with are training/checkouts/logging minutes and I'm just another person to help fill the boat so it will run the trip. Pict below with some RB friends and me without a loop.
