I am stuck and frustrated. Client has their travel site run by Wordpress, mainly for Content management systems functionality. Presently I am attempting to enhance the Content management systems functionality (their previous developer did not deliver) utilizing a custom publish type plug-in (Custom Content Type Manager). While its performing typically its tiresome producing the fields for that custom types and pops up short when it comes to ease of use when entering/adding content (from the client's perspective). Its beginning to appear like Wordpress + custom publish type is simply not the very best solution for what they need to complete, but due to some time and budget I am tied to it.

I've maybe one further gamble I possibly could take with this particular project... any applying for grants a much better solution than custom publish types?

Why don't you just create some publish templates and also have them choose the right one based on which kind of content they're entering?
