Need RV parking in Seattle for a 14 day cruise

[Need RV parking in Seattle for a 14 day cruise]

We are driving our motor coach from Florida up to Seattle this summer, then going on a cruise for 14 days to Alaska.  

We are looking to park our 42ft.  RV somewhere where we could have electricity to keep the refrigerator running.  We had hoped not to have to pay full RV park rates for that many nights.   We've already checked with Lake Pleasant RV park, they do not have any openings.  It looks like cruise terminal parking could be upwards of $35 a night :-(.  

Does anyone have any suggestions on who we might be able to contact for this?

Thanks,

John & Jackie Tice

(P.S. We are also looking for a dog sitter for our beagle Holly!)

I have a 2015 4X4 LB.

I just installed the Blue Ox baseplate on Saturday. As soon as the weather clears up a bit I'll finish the Air Force One install. Still have not decided on what to do about lights on the toad. I'm not going to drill holes in the taillight assemblies.

Leaning toward installing diodes and using the factory lights.
