Writing doesn't necessarily have to be hard. You could have written about things you were worried about the business or silly quirks of someone staying with you or whatever. They don't have to be long posts. You could just do a short update or a small little freewrite about something on your mind.

As to your business, I wish you luck.

It makes sense to expand it into tours or some such. People can book flights and such online these days. They can search for the best prices. Of course, that too takes a lot of time. It takes even more time to plan a trip though. I myself have no clue what I would want to visit in various places. I can only think about places where I would like to stay. Standard tourist spots don't appeal to me, because they are so crowded and require so much walking. By the end you're just tired and annoyed. It's not fun. Having someone to find places that you would want to go to and see, that is valuable. That's reason to hire someone to help plan a vacation.
