With HGVC you primarily get the HGVC Developed Resort Areas (Orlando, Las Vegas, South Beach, Oahu and Big Island), limited access to most of the HGVC affiliated resorts and RCI membership.
Unless you want more of the same, here are three suggestions...
(1) Take Advantage of the RCI Getaways instead of buying another timeshare.
Your HGVC RCI membership gives you access to RCI getaways. The sad thing is that we don't get online access with our membership to see what's available however you can take a look at RCI's public rental website to get a general idea - see
http://www.wyndham-vacations.com/
For example, I compared the dates and rates for Morritt's Grand Resort (#5930) using my separate RCI account.
The public website only shows a rolling 12 month calendar (Mar 2009 to Feb 2010) vs the RCI Extra Vacation shows availability until August 2010. However the public website is showing all of the weeks that are available during the 12 month window. The prices are slightly different (higher on the public website) but perhaps the RCI Extra Vacations isn't showing the additional taxes and fees in their total price. I'm not sure.
NOTE: All resorts don't show up on the public website. For example, the new Parc Soliel by HGVC is currently available on RCI's Extra Vacation but not on the public website. So if you're interested in a particular resort I would try the public website first for availability if not then call the HGVC RCI Desk to determine availability.
If you decided to rent, I suggest comparing the total price and terms & conditions for both (public website and the info you get from the HGVC RCI desk) to see which one is the better value.
NOTE: Sometimes weeks available in RCI's Extra Vacations are also available for a RCI exchange

(2) Rent timeshares/condos/homes instead of buying another timeshare.

Exchange Companies are also renting -

don't require you to login to see their rental listings and don't require paid membership for access to their rentals like Trading Places, Hawaii Timeshare Exchange and Platinum Interchange)
(3) Buy into a different timeshare system

Whatever you decide, don't put all of your future vacation dollars into timesharing. This will give you the flexibility in the future to choose the best way to visit your desired destinations. There might not be a timeshare at the location that you want to visit or if there is a timeshare it may be very hard to get an exchange. You may also want to visit a destination in an entirely different way via a cruise, hotel/resort stay, special discounted travel package, tour company, etc....
