Well I've done it. I've got the entire US dotted with timeshares and you can see them at my
new Timeshare Map page. I had to rewrite the javascript to keep in line with the new version that Google released. While doing that I also combined the individual pages into one page with buttons at the top for the different regions. I wish I could just dump all the US markers onto the map, but it chokes when there are large quantities of markers and I'm right at that limit.
It works in Internet Explorer, it works in Firefox.
I added a few new colors to make it easier to select II and point/weeks, plus an 'other' marker for other timeshares that aren't really timeshares. I haven't really used this 'other' marker much, but I'm thinking I'll put the RCI timeshares marked Rentals in that category.
I have found that not all the timeshares are in the TUG database. My next task is to go through the RCI and II catalogs and add the missing timeshares.
I'll be taking the other pages offline soon.
