Hi Robert:

As for the pricing part: With the existing GoodRelations / schema.org elements, you are able to cover about 90 % of the pricing scenarios already off-the box.

For an overview, see

    http://wiki.goodrelations-vocabulary.org/Cookbook/Pricing

When using this in schema.org, note the slight naming differences, listed here

    http://wiki.goodrelations-vocabulary.org/Cookbook/Schema.org#Naming_Differences


For the remainder, we need to add a few selected elements. 

For 2014, I have on my agenda to translate the accommodation extension for GoodRelations (http://ontologies.sti-innsbruck.at/acco/ns.html) into a proper schema.org extension proposal.

With only about a dozen additional types and less than twenty properties, we would cover the whole hotel / camping etc. field. See the examples at

Services often have rates rather than unit prices (e.g., lawyers’ hourly rates), criteria for fulfillment and completion, are typically time-bound (per month, per year, etc.) and have terms and conditions substantially different than products.  When one considers the range of LocalBusinesses encompassed by Schema, many (if not most) are rendering services rather than selling products.  Service is literally an intangible, and should probably be located as a subclass of Intangible.   It also forms part of some proposed extensions for LodgingBusiness.

If the itemtype attribute is missing or parsing it in this way finds no tokens, the item is said to have no item types."
