Just a little bump since there has been some related discussion in other threads.
DH and I have been looking it over. Awesome, time consuming job. Did you see any big difference in 400 and 500. We've stayed in 500 and liked it. Not sure whether to try 400 or stay put.
Glad to hear you appreciate the map. As for 400-500 comparison, I really prefer 500. According to my recollection and impressions (i.e. this is opinion) 400 is less shady and feels more cramped, probably because of less vegetation. It is closer to the marina so it is a bit more convenient.
