My take on Arcadia would be similar to those who have posted in this thread that it's good for a round every now and then. If it was less crowded and less expensive, I'd go every summer. Instead, I would prefer to wait for the late fall when the pace of play is faster, even if the weather is nasty. I found the course easy to walk, but realize I may be in the minority on that view. In terms of the actual golf course, I liked it quite a bit. If you're able to get onto Crystal Downs, it makes for the perfect companion course for a 36 hole day since they're so close logistically.
I wouldn't put it in the same league as Crystal, Kingsley or Forest Dunes, but I wouldn't put most courses in that league, so that's hardly an insult. The holes along the lake are a lot of fun to play, and I loved that par 5 going down towards the lakeshore, #11 I believe. And definitely add me to the list of people who enjoyed the flagsticks.
