Quintessentially disappointed
I recently quit Quintessentially due to a string of disappointing incidents. First, I found their "exclusive" access to be overstated. Sure they have connections at a few spots, but when it comes to restaurants they got the same results as I would have gotten (and I tested them on this more than a few times). On several occasions they mis-read my emails and booked tables on the wrong days/times.
Keep in mind that the staff at Quintessentially are young and probably not too well paid, so their knowledge of the best hotels, restaurants, shops, etc. is not first-hand. In one case the rep I spoke to was unfamiliar with basic NYC neighborhoods.
When it comes to managing basic tasks they were fairly inept. I asked for help in finding a new place to park my car and they were unable to do that. When I actually found the time to do it myself it only took about half an hour, so I'm not sure what their problem was.
When I made management aware of these issues they gave me a string of excuses, basically saying that they're a start-up company that's growing too fast without enough office space, etc. As you can imagine, that's not a good answer to give a disgruntled customer. They finally agreed to refund my membership fee, but only the unused portion. Again, not a good answer.
Basically a waste of money IMO.
