Where to Check In: The Hilton Pier at Waikiki

Where it actually is

There is no submarine terminal at Waikiki. Check-in happens on a pier belonging to a hotel, and the hotel is one of the largest resort complexes in the state.

The specifics matter here more than usual: the Hilton Pier, in front of the Hilton Hawaiian Village's Ali'i Tower, next to the Tropics Bar. Three landmarks, and you need at least two of them to find it confidently.

The Hilton Hawaiian Village is not a hotel in the sense of a building with a door. It is a resort of multiple towers, lagoons, pools, shops and restaurants covering a substantial piece of Waikiki, and crossing it on foot from the wrong entrance takes real time.

The consequence is simple and it accounts for most of the stress anybody experiences on this trip: know which tower before you set off.

Finding it without a panic

Look at the location on a map the night before rather than on the morning. It takes a minute and it removes the whole problem.

Aim for the Ali'i Tower specifically rather than for the resort as a whole. If you are being dropped off, that is the name to give the driver.

The Tropics Bar is the close-range landmark. Once you are at it you are at the pier, and the check-in desk is on it.

If you are walking from elsewhere in Waikiki, allow more time than the distance suggests. The beachfront path is pleasant and busy, and the resort is at the western end of the strip.

And if you are staying at the Hilton itself, this is straightforward and you can ignore the whole section.

The twenty minutes

Check-in is required twenty minutes before the scheduled tour time, and the reason is structural rather than administrative.

The submarine is moored offshore. A surface boat leaves the pier to take passengers out to it, and that boat has to depart in time to meet a vessel operating to its own schedule with the next load of people already checking in behind you.

So the twenty minutes covers checking in, being counted, being briefed and boarding a boat. It is not slack, and it is not a soft deadline: a boat that has left cannot come back for you.

There is no later group to join, because the next departure is a full one with its own passengers.

Arrive with margin. Thirty minutes rather than twenty buys you a short wait beside a bar in Waikiki, which is hardly a hardship.

Parking and getting there

Hotel pickup and drop-off is not included in this booking, so reaching the pier is your own arrangement.

For most visitors that means walking, which for anybody staying in Waikiki is realistic, or a short taxi or rideshare to the Ali'i Tower.

If you drive, parking validation is available for purchase at check-in and covers a few hours, which is more than the trip needs. Ask about it when you check in rather than afterwards.

Resort parking in Waikiki is otherwise expensive and busy, so the validation is worth taking.

What happens at check-in

It is quick and it is not an airport. Your booking is confirmed, the group is counted, and there is a short safety briefing covering the transfer to the submarine and the ladder.

This is the moment to raise anything: a child you are unsure about on height, a mobility question, a tendency to seasickness. The crew would far rather know at the pier than at the hatch.

It is also the moment to ask which side of the submarine will see more on today's route. They know the plan and will generally tell you.

Then it is onto the surface boat and out to the vessel, and the day proper begins.

If you are late

You have missed it, and it is worth being blunt about that rather than leaving room for optimism.

The boat leaves on time because the submarine is working to a schedule, and there is no mechanism for catching up with a vessel that is already offshore.

Whether a late arrival can be moved to another departure is a matter for the operator and the terms of your booking, and it will depend on whether a later slot has space. In the busier part of the year that is often no.

The whole problem is avoided by treating the twenty-minute check-in as a thirty-minute one and knowing where the Ali'i Tower is before you leave.

Getting back afterwards

The trip returns to the same pier, which sounds obvious and is worth stating because a certain number of people arrange a pickup at the wrong end of Waikiki.

You come back to the Hilton Pier, in front of the Ali'i Tower, and disembark where you started. If somebody is collecting you, that is the address.

Because the whole thing is under two hours, most people simply carry on with their day from there. The resort has food and shade, the beach is immediately there, and the rest of Waikiki is a walk along the front.

If you drove, this is the point at which the parking validation you bought at check-in earns its keep, so keep it somewhere you will not lose it during a boat trip.

Before you book

Finding the pier

1. Save the location the night before

   A minute of preparation removes the entire problem.

2. Aim for the Ali'i Tower

   Not the resort in general. That is the name to give a driver.

3. Look for the Tropics Bar

   The close-range landmark. The pier and the desk are beside it.

4. Arrive thirty minutes before

   The requirement is twenty. The margin buys a short wait in the sun.

5. Ask about parking validation

   Available for purchase at check-in and worth taking if you drove.

6. Raise anything at the desk

   Height doubts, mobility, seasickness. Better here than at the hatch.
