Before deciding
These visible answers match the clean page's structured guidance. Broad evidence still cannot establish your exact date, party fit, or live provider total.

No. The broad activity evidence does not prove that Oahu: Grand Circle Island and Haleiwa 9-Hr Deluxe Tour: Full Day Tour: Circle Island is available for your travel date, that enough seats fit your party, or that a stored price still applies. Run the exact-date check, then confirm live capacity and terms with the provider.

Listing comparison
Paste a different Viator activity. This tracked activity family stays the baseline, and your current date and party carry into the result.
Only a tracked, supported, different provider family counts as a real comparison. Untracked, invalid, and same-family pastes stay diagnostic. We retain the normalized provider and product identity, not the raw pasted URL or share text.

Bookable options
Compare the named option, its status for your date, observed party-tier fit, and latest tracked price. Party fit does not confirm seats or calculate a party total. Every provider button stays tied to that same row; confirm the final date, party size, price, and terms there.
