The corporate accounts are a benefit of the vacation club you belong to (HGVC, DVC) and you are reliant upon the club to search inventory and book through them, at least with HGVC. Each system has a limited number of club properties, so having the option to exchange within RCI provides more options and value for these club member owners.
An individual RCI account gives you direct access to the on-line system where you can search the system yourself, learn what's out there, play with options and figure out the angles and deals. Some resorts are only RCI weeks, some are both weeks & points. Often an owner must convert their week to points to be part of that program or purchase a week resale which was already converted by another owner.
Points accounts let you access the weeks side of the system as well. Traditional weeks accounts as I understand it has you depositing your week into the system and see what trading value your week has by seeing what comes up as available exchanges.
The entire thing can go off into many directions and if like me you have multiple weeks in multiple systems, keeping it all straight can be a challange. :hysterical:
The week we own which is not officially closed yet...but close...is Las Vegas Desert Club (aka new Summer Bay) and the wee through which I have an RCI points account through. With it, I can get into all of the other places I own, except for Gardens @ W.Maui which exchanges through Interval International...a separate exchange company. The advantage of owning these other properties is they make it easier to obtain high demand/season stays vs: attempting to exchange...although we were discussing just today whether or not it might make sense to do more exhanging with points account and getting rid of one or more of the weeks we have now once the market stablizes.
