why are houses on the beach built on stilts, but hotels on the same beach are not built on stilts?

Probably weight.
A reasonable number of wood posts/stilts could support a house.
Supporting the weight of a big hotel is a different story.
Here in California, continuous foundations are usually required for earthquake safer. You cannot have any big gaps, such as between “stilts”. As a result, out beach houses are built on higher ground, often using concrete retaining walls or sloped earth:

They essentially are. High rises are typically built on top of concrete “piers” of a specified diameter, and drilled to a depth that achieves the necessary bearing capacity for the calculated load.
Geotechnical engineers will take samples to determine whether there is bedrock with sufficient bearing capacity, or if they need to rely on the friction between the piers and the ground.
