I think it is a relative thing. We are finding Grenada much more crowded now than five years ago even if the number of boats here is probably no different. It is just that we have spent several years cruising in places where there were few (and in some places, no) cruisers. From my perspective you get two types of cruising grounds. In one there are enough cruisers for there to be a 'cruiser society' and a 'cruiser economy'. In other areas, neither exists and you are just part of the local harbour or anchorage scene. Coming from where you have cruised you likely will find most places crowded. For someone coming from the western Med, the same places will feel uncrowded.
