Having been in/out of USA many times, I can honestly say, we have been treated with nothing but courtesy and politeness by Homeland Security staff, even interest in our visit. This is contrast to passport control back in Blighty where they are not at all friendly when welcoming their citizens home! Hopefully your experience was just a one-off! If you google the airport details, it will give different options for travelling into Seattle.
I totally agree with Marshall, even at the height of security, post 9/11, US immigration can a slow process but we have always been treated with courtesy, a laugh & a joke, & enjoy your visit. Your lucky if you get a 'grunt' as a welcome home from UK Immigration! Maybe your man forgot his happy hat as he left home that day. Regards Wilba.
Taxi fares are very reasonable - there seems to be a fixed charge but check before travelling to fix the fee. About $30 should be the cost for a car-type taxi - more if you need a van-type. Border control depends greatly on where you enter US. Always make sure your documents are filled in correctly as you will have to do them again if they find any errors. Be polite, they are only doing their job. Do not joke about terrorism etc. Keep the conversation to the point and honest. They often ask questions like - is this your first visit to the USA? - or when did you last come to the USA? Answer truthfully (they have your visiting record on their computer. Most officials are freindly and wish you a pleasant stay. Enjoy Seattle, don't forget to go to Pike Place Market. Good luck John B.
I can't answer the question re the cost of the taxi however my very recent experience of traveling from Vancouver to Sea-Tac was not without problems. Firstly the border crossing we choose (Alder Grove) took in total 3 1/2 hours! This was simply due to the volume of traffic on a Saturday morning. Apparently lots of Canadians like to shop in the US. The official time (You can get details on the radio) was 1 1/2 hours. The US officials were cheerful and polite, no problems there. So please allow plenty of time and perhaps, if possible don't cross the border at the week end. The route we choose back to the airport was okay but we had at times slow moving traffic because of road works etc.
L stayed in Seattle this summer and a taxi from the airport to the cruise terminal was then about $34 lf you have time while in Seattle visit Pikes Market it's only about a 20 minute walk away from the cruise terminal although it is up a very steep hill but it's well worth the trip it's a huge craft market and food hall and well worth the trip.Brunch at the Space Needle is another thing not to miss although you will have to pre-book,the resturant revolves while you are eating so you get to see a 360degree view of the Seattle skyline and it's absolutly breathtaking. Have a good trip wish l was going back again real soon. Bon voyage. Jan Clark .
