Welcome to the Q&A Forum

Definitely go for Option 1: redirecting to the relevant pages on the singular domain. I would also recommend using subfolders to contain content on individual locations, something similar to rapturecamps.com/bali for Bali information. This would allow you to gain authority for that specific niche and add articles to that niche, rather than having them all under one central holder (the root domain).

Yeah i have though about it in more detail as well. I mean i understand that link farming is not the way to go. But there are allot of persons out there having there own blog. We also had allot of past customers wrote a blog post about there experience with us which we cant really control. They have putted a link into there post, so how would google know which post is paid for which not. Of course you would always need to work together with legit hight quality blogs to secure your interested and getting onto spamming blogs.
