See Wikitravel:What is an article?. The general rule is that if you can sleep in a place (for example, if an island has a town on it) then it gets its own article. I'm not sure where Cayo Coco or Cayo Guillermo would fall since I'm not familiar with either place. -- Ryan 02:46, 20 Feb 2006 (EST)
Should have read the parent article more closely. If the islands only have single resorts on them then they can be included in the Jardines dey Rey article. See the Perhentian Islands for an example of a group of islands that was created as a single article, and Galapagos Islands for an island group created using multiple articles. -- Ryan 02:49, 20 Feb 2006 (EST)
There's actually about a dozen hotels spread over the two islands. I suspect that visitors will look for Cayco Coco or Cayo Guillermo rather than "Jardines del Rey", but I am not sure there's enough information there for three pages !

Dont worry too much about the pages being short -- you'd be surprised how detailed a guide an get. If there are more than one resort on each island I'd go with splitting them up for sure. Majnoona 12:08, 20 Feb 2006 (EST)
