This is part two in an occasional series of Unsolicited Pieces of Advice for my fellow travel bloggers.
What you didn't see doesn't matter. Stop feeling like crap because you didn't see X and Y on your recent trip to Z city. Seriously. Stop it.
Any fellow travel writer who judges you for not seeing a particular museum or eating at a particular food stall is dumb. This is not to say that you shouldn't thank people for providing you with tips, of course—more on that, perhaps, in a future Unsolicited Piece of Advice—but stop worrying about what other travel writers and other people think. Just do your thing and write about it in a compelling manner. Or enjoy yourself and take notes and don't publish anything at all.
One of my favorite travel companions hates going to any destination that requires major effort to visit, only to find that she doesn't have enough cash on hand to partake in the iconic local activities. I get that, but even here I think that whatever happens is going to be interesting and worthwhile. $500 whalewatching excursions can piss off.
Great writing is great writing. The best travel writing—even narrowly-defined "service" writing—often isn't really about activities. Remember this, and stop fretting over whether or not you've ticked off every last item on the must-do list.
Here it is, again. What you didn't see doesn't matter.
