The hack, step by step
- Pick the home membership you'd use most locally (e.g. Maryland Zoo CoRE $180).
- Check that your level is reciprocal-eligible on the official list.
- Before a trip, call the destination to confirm current reciprocity and guest limits.
- Bring membership card + matching ID; buy at the gate if online won't apply the discount.
Special events, IMAX/planetarium and parking are usually excluded.
