Tulalip Casino

from Mike, September 11, 2009
Stay there about 6 times a year to shop (outlets & Walmart) and gamble. Good size lot but some spaces have been taken up with ATCO trailers while they built the hotel. Park at back of lot for quietest area. If lot is full park in the NW corner of the car parking lot. Exit 200 or 202 off I-5 works. If you want to sleep, don`t park there on a US holiday... fireworks ALL night. Great buffet in the casino.

Check this place out. I see many RV 's parked there all the time. I myself don't gamble, but the food in the casino is great. This place is right off of I-5 in Marysville WA.
 
Editor's Note:
I looked at the web site, and it seems like a very nice place, and clearly RV friendly. They have a large RV area and allow dry parking for up to 7 days. They even send a shuttle around to pick you up!

No hook ups - they ask that you call them and let them know you're there and they'll bring you a pass. We called and let them know but they never brought us a pass. We didn't eat there but went in and played $20.00 each on the 5 cent slots. Security is great. Location is great off I-5 and there's a big outlet mall if you're into it.

Not much to add. Another non-smoking casino. Parking lot is good. Food and service was great in The Cedars. My praise to the waitress. The CEO's order wasn't quite right and she came back in about 30 seconds and said the she was a little suspicious so she was checking back. Brought another meal for her that was much better.

You apparently need players card. I called the security as per the sign in the lot and told me to get a card then call back from RV and then they send security to check you in. All is well.
