One thing to consider is that there’s no commitment or deposit you need to make to keep the RCC option open. The SIR deposit for Merced is only $250. It might be worth that much to keep the option open. You can always pull the plug and decide later to go to RCC instead. But if you let the commitment date go by, then the Merced option will be gone. Maybe if you deposit, you’ll be able to get out there for a visit before you make a final decision. If you did contact the water polo club, maybe someone from the team would be willing to show you around and talk about what it’s like there.
