Residence Inn Seattle Downtown/Lake Union

Old wooden boats on the docks, and peapod rowboats to borrow first come, with a volunteer helping kids aboard.

A Kid-Struction Zone for ages 2 to 7 and hands-on Idea Lab activities, so small kids build while older ones work through the city's past.

Small hillside play area with swings and climbing, looking out at the Space Needle and downtown.

Museum of music, gaming and science fiction collections, next to the Space Needle.

A 30-foot climbing tower with long tube slides, so older kids get a real climb, plus sculptures that play music.

A heated indoor pool that is never deeper than four feet, and a walk to the science center and the kids' museum.
