An Airbnb pricing strategy is the set of rules that decide what each night is worth: base, minimum and maximum prices, seasons, events, minimum stays, gap nights, last-minute pricing, length-of-stay discounts and channel markups. The tool applies the rules; the strategy is what makes the tool worth having. Smart Pricing is not a strategy, because it optimizes for Airbnb's fill rate and knows nothing about your events or other channels.
What I plan around in Carcassonne: the medieval Cite de Carcassonne; the Bastille Day Embrasement de la Cite; the Cathar castles of Montsegur and Peyrepertuse; Festival de Carcassonne. Guests I price for: heritage travellers and touring families on 2 to 4 night stays in the walled Cite and the Bastide Saint-Louis lower town. Where I start: a concentrated summer peak around the Cite and its 14 July fireworks, dispersed Cathar-castle touring, and French meuble de tourisme registration.
I configure PriceLabs or Wheelhouse with you so the 14 July fireworks and the festival concerts are loaded as events, touring two-night stays are allowed in the shoulders, and Booking.com, Vrbo and Abritel all reflect the same rules and taxes.
The service in general is described on my airbnb pricing strategy page; this page covers how I apply it in Carcassonne.
