My experience comes from kayak. No trailers to deal with.
The tourist places will shuttle their clients that rent from them, and take your personal yak if you ask pretty please. However, these are not generally the places I'm looking to float, as they are stacked with 300 other people putting in and taking out at the same places and it's a floating party, not exactly what I'm looking for. They're tourist summer fun destinations, not catering to anglers.
I want to float Penns, the J, Bald Eagle, Pine through the gorge, Skuke, Little Skuke, Swatara, and other such smaller waters. And a creek yak is a fantastic way to reach large stretch of water like this! There aren't these massive tourist operations. Shuttle services don't exist.
If someone's comin with me and has their own car, easy peasy. Even better both cars haul the yaks, saves a trip. But, if I'm alone, or even if with somebody but it's a 5 hr trip and we don't wanna bring 2 vehicles, it's definitely tougher.
