The K West Hotel's influencer marketing action plan involves four main strategies: 1. Host monthly theme parties at the hotel's spa, kitchen, etc. and invite influential bloggers and press to gain visibility through their posts and reviews. 2. Create partnerships with green associations and communicate the hotel's involvement to encourage "eco-friendly" guests to talk about the hotel. 3. Organize a contest for guests to design a future guest room, with the winner receiving a weekend stay after their video submission is posted online. 4. Develop the hotel's own blog featuring employee videos and articles about the spa, chef's recipes, and more to position the staff as influencers themselves.
