I think there are many programs out there that do not require an audition and hence body type and experience will not factor in at all. Finding programs near the beach, however, does severely limit options. Members here could probably suggest many non-audition programs if there are other locations your dancer would be willing to consider.
St. Mary’s College (northern CA); Goucher College (Maryland); Pacific Univ. in Oregon; University of Kansas (BA does not require an audition); University Colorado Boulder; Barnard, Skidmore… there really are quite a lot of programs out there.
