Planning your next step
Check the camp year before acting on a registration message. If an older page is still available, ask the organizer for the next current session instead of assuming the same dates will repeat. Mariners alumni can help by separating lasting preparation advice from details specific to their attendance year.
Before you commit
- Get dates, venue, eligibility, and the playing format in writing.
- Compare the full cost, including travel and anything outside the package.
- Read cancellation terms before paying a deposit.
- Ask about accessibility, companions, and any participation requirements.
