Every SEO project has the same progress but with each field there're some differences.
For detailed suggest travel guide sites my suggestion should be.
1. Research Keywords

be sure you know the tool)
- Begin with travel guide in general
- Go deep down into your target field
- list the potential keywords (which have high search volume)
- Don't forget the longtail keywords, they are good when being used for content.
2. Optimize site
- Keywords density should be careful.
- Metas ( H1, H2, H3,... Title, description)
- Img Alternative tags
- Fluent content
3. get some more traffic by some kind of channel: facebook, tweet, ....
It's not the most detailed suggestion but I hope it can help you. xD
