Agreed that the regexp wouldn't work for your code.  I would have
written it like this (like I said before your code is cleaner)

def check_age
  print "Please enter your age: "
  age = gets.chomp
  target = 18..30
  valid = /\d{2}/

  if valid.match(age)
    if target === age.to_i
      puts 'Have A Nice Holiday'
    elsif age.to_i  < 18
      puts 'Too Young'
    elsif age.to_i  > 30
      puts 'Too Old'
    end
  else
    puts "Usage: <18..30>"
    check_age     # Try again
  end
end

check_age
