GET /api/calendar-hotels returns the calendar hotel of every visible
product, with the products using it and their season, behind the same
API key as /api/hotel and /api/product.
MyE&P only syncs contingent snapshots for its accommodations, so hotels
that are only offered in winter (e.g. DKI, DWW, ASCGR) have no
availability for the iCal feed and the availability calendar. With this
list MyE&P can sync every hotel code TYPO3 actually uses, without a
second list to maintain. The products and seasons are for a status
overview of which hotel supports iCal, availability and prices.
Hidden hotels are left out, as on the website (e.g. ASB).
