We were just there at the beginning of February for a night in a slip at Marina. We arrived at about 11 am or so and departed about lunch time the next day, just the Admiral and myself.... our excuse for the bareboat charter was to celebrate our 50th Bdays....
So, we really enjoy Scrub for an overnight stay during the charter.
We, alike a lot of others, don't like to have a set schedule/itinerary, so I just call them the afternoon before our arrival (I think the number I used is 284-496-0304 direct to Scrub) and make a slip reservation.
A few weeks ago when we were there, we were on 44 ft mono and I think our total cost for the overnight was about $130 or so. For the first time we had breakfast up in their dining room and it was fantastic, and the cost was reasonable.
Have fun!
