I'm a beginner, but I would do like this:

class Reservation(models.Model):
    properties=model.CharField(maxlength=7,primary_key=True)

class Restaurant(models.Model):
    name=models.CharField(maxlength=30,primary_key=True)
    reservations=models.ForeignKey(Reservation)

class Theater(models.Model):
    name=models.CharField(maxlength=30,primary_key=True)
    reservations=models.ForeignKey(Reservation)

class Hotel(models.Model):
    name=models.CharField(maxlength=30,primary_key=True)
    reservations=models.ForeignKey(Reservation)

Use ForeignKey or ManyToMany as you need.

Enjoy,

G
