Hamvention Buses

Hamvention Buses

Buses will run from the hotel door to the Hamvention entrance on Friday and Saturday.

This service makes it really easy to get to and from the Hamvention. If you drive you are likely to pay just as much in parking fees and be faced with a long walk to the Hara Arena.

On the outbound route buses will be available from 7.30am until 9.30am. Pickup is at the main entrance of the Holiday Inn.

Return journeys will run from 3.30pm until 5.30pm - your driver will agree a pickup location. Be sure to listen and be at the pickup point no later than 5.30pm

Ticket prices will be confirmed later ($15 in 2013 and 2014). Each ticket will cover outbound/return journeys on both Friday and Saturday.

You can buy your ticket at the hotel during Wednesday evening registration and throughout the Thursday events.
