Having used many livery and limo services all over the world, Hoyt Livery (New Canaan CT) is by far the worst.
Inflexible and unwilling to work with clients other than on their terms. I tried using Hoyt on a recent European trip. When my returning flight changed due to business issues they still charged me for the unused airport pickup ($200+) and refused to discuss, credit or adjust the cost.
There are at least 5 other car service companies in Fairfield County.
Do not use Hoyt Livery. Use any other than Hoyt (Rudys, Nutmeg, Leros, Fairfield are all reasonable and comparatively priced).
Monetary Loss: $200.
