If it weren’t for the fact that Auckland is at level 3, I would be asking my husband to whisk me away for a weekend – the location looks beautiful.
I agree with Annabelle and in addition you might want to try:
LinkedIn: reach out to the professionals in the Auckland market needing to escape the city for a relaxing retreat. Perhaps offer an incentive for weekday bookings (I took a look at the calendar and see mostly weekends are booked out). This market will also be more likely to book online as you are wanting.
Call to action: create an offer for couples – the romance weekend (at a higher price point) that includes a bottle of bubbles and cheeseboard on arrival, rose petals for the outdoor bath :), a basket of local produce for breakfast etc. For Tolkien Movie buff couples, can you combine the accommodation with the Hairy Feet Tour tickets?
Cross-promotion: make sure that the businesses you are promoting on your website under activities are promoting you in return.
Go well, and I might see you in a lower level- ha!
