Travelzoo offers an Adult Ticket to the Penn & Teller Show at Rio All-Suite Hotel and Casino in Las Vegas, NV, with prices starting from $46.40 via coupon code "ZOO". That's tied with our mention from last week as a savings of $31 and the lowest price we could find. The Los Angeles Times calls this show "the single best show in Vegas" and TripAdvisor awarded it the Certificate of Excellence. Additional taxes and fees apply. Book this travel deal by April 30 for shows through May 31.
