To be fair, the bread and butter for most travel agents was booking flights, cruises, and tour packages. Which is why the corner travel agent isn’t around any longer for the most part. Yes, some were more knowledgeable. My parents used a couple of them over the years.

These types of travel agents still exist but they’re generally specialty travel, adventure travel, etc. companies that handle a combination of group trips with guides and private trips with or without guides. Besides the big global ones there are many that concentrate regionally and/or in a particular type of activity.
