The IAG has reserved 4 boats that can accommodate 10 people each. Enjoy a self-guided floating party. See the Sleepless in Seattle house boat, explore Lake Union, the locks or Portage Bay for 2 hours with your Gnathology friends. If it’s hot enough the more adventurous can swim right from the boat.
Cost is $35 per person. Limit 40. Sign up at the registration desk.
