We did the morning tour and it was most enjoyable. Small group numbers make for a more personalized experience and you don't need to fight your way thorugh the crowds for a tasting. Most of the tastings were generous and most places we visited were informative and gave a perfect insight into what the Swan Valley is about. Only irk (through no fault of the tour operator) was the fact that people had to be reminded not to double dip. In this day and age surely we should be informed enough to know that this is not the done thing. - unfortuantely though there were still people doing exactly this. All in all a great morning out will look forward to doing the afternoon tour when we return to Perth.
The whales are simply magnificent and we had numerous chances to view them. Downside was the number of people on the boat so you felt you needed to fight your way through so see the whales at times.
For his reason I would look for a smaller tour operator if we were to visit the whales again.
