Best Seattle pier to Seatac for party of 11?

We are a party of 11 and I need a recommendation for the best shuttle service to contact for pier to Seatac service. Our ship is the Carnival Legend and will dock at 7:00 on a Tuesday and our flight is as 12:20 so we plan to bring our bags with us as time will be a factor. Any recccomendarions will be appreciated. Probably just looking an entire 12 passenger van.

A little reading on the board would reveal the transfers company like AlreadyThere are the common recommendation.

As previously mentioned, Already There gets good reviews on this forum. You might also check with Seattle Express and Shuttle Express about their private vans.

For a 12:20 flight you won't need to be off the ship until 9:20/9:30am. Or , ask aout a brief sightseeing tour and leave the ship by 8 ??
