I think this is a fairly clear case for the Horizontal Layers guideline 
and Simon also made a statement in that direction.  Of course as always 
this is a matter of interpretation.

I would also suggest to keep in mind that in principle this is exactly 
the kind of case share-alike was created for - the OSM database is 
missing some hotels and some other database contains them and the 
intention is that you need to make available that other data or the 
merger of the two data sets for inclusion in OSM if you want to use 
them in combination.

If your use of the booking.com data is not about hotels missing from OSM 
but only about the additional info booking.com provides (link to 
booking page and other metadata for example) the new collective 
database guideline gives you another option: you can match this 
metadata with the OSM POIs and use them together without share-alike.  
You however must not show any hotels that are not in OSM then or make 
their coordinates available under compatible license.
