Yes, this company is a ripoff. National Park Reservations is very good at search engine optimization, so they often appear at the top of a search list. National Park Reservations charges a 10% fee above the cost of the reservation, which is disclosed in small print--especially if you end up in the middle of the site from a search engine.
You start by making a reservation request--this doesn't necessarily book the reservation. When I made the reservation request, they then called me back. Since they called me, I did not hear the warning on their phone number that says they charge the fee (I only heard it when I called to complain). If this was by design or mistake, I can't say. After talking to the sales rep, it was not clear that the 10% fee was on top of the other charges. Only when I got my credit card statement did I realize what this firm had done. There were two charges--one for the reservation and one for the "fee". NPR charges exorbitant fees for a simple service.
When I complained, the firm did refund half of the fee, but I still feel victimized.
Avoid this firm at all costs. They hide behind disclaimers and fail to do the right thing when confronted about their deceptive practices.
I should have read the fine print more closely, but I give this warning so all of you will hopefully avoid National Park Reservations and the problems I encountered.
Good luck when dealing with this firm.
