One of the hallmarks of 21st century schools and non-profits must be flexibility. We can't just pack up and quit when things don't go as they have for the past three centuries.
We have operated a hybrid Web-and-SL school on the mainland for nearly three years now. We can adjust the size and complexity of the main campus, the number and location of remote facilities, and generally accomodate any changes in current needs and budget.
Go to the mainland. You will have all the control you ever need.
