I just got back from a week's vacation, which my wife and I spent at
Elmhirst's Resort, in southern Ontario's 'cottage country'. It had been recommended to us by a pilot friend (and his wife) as a nice place to obtain a seaplane rating in a relaxed environment equally hospitable to non-flying spouses. We found that to be accurate.
The accomodations were great, and the prices reasonable: C$1,099 (about £446) for the
flying (six hours dual, one hour solo), and C$1,282 (about £520) for the
"deluxe cottage" (located 20 seconds' walk away from the floatplanes, and 30 seconds' walk away from the grass airstrip). The airplane used for training was a PA-12, which seemed to be in good condition and was fun to fly. Training typically began (with float pumping!) about 0730 and was finished by about 1000, leaving us with the better part of the day to spend together.
