I'm not positive, but I doubt it. NAS Whidbey is fairly strict/picky about letting people on base without a base pass or with non family members accompanying someone with access. Your best bet for a "tour" is with a family member with a military ID. Or maybe ask the people at the ID card place at the Langley Gate of NASWI.
CM made it pretty clear so nothing to add but Dito.
