Travelzoo offers an Adult Ticket to Real Bodies at Bally's in Las Vegas, NV, for $19. That's tied with our mention from two weeks ago as the lowest price we could find by $9. This exhibit uses preserved human specimens to explore and illustrate different facets of human physiology. Book this travel deal by December 23 for tickets through the same date.

Of note, you can also buy two Adult tickets for $35 or a Child's Ticket for $10. Those are the best deals we could find by $20 and $8, respectively.
