I presume the same is true of other seasonals? Generally, yes, except the Schmoochle takes up two beds (one for each head).

Keep in mind, however, that earning coins quickly also means you have to visit the monster more frequently, since they'll earn 100% of their available income within a few hours. By comparison, I have an island full of ethereals who I only have to visit twice a day.
