A few tips on the Sandy River Front RV Resort:
We have only accessed the RV park from the downtown Troutdale side. We have not taken the I-84 Freeway Exit #18 that is on the East side of the Sandy River. We do not recommend using that Exit #18 which will require driving South upstream on the East side of the Sandy River and turning onto a very narrow bridge just 100 yards from the RV park's entrance. We recommend using the I-84 Exit #17 which will put you on NW Frontage Road. The Westbound I-84 Exit #17 is about 1/2 mile East of the Eastbound I-84 Exit #17. NW Frontage Road makes a one-way loop, counter-clockwise, with the loop ends going under the freeway. Thus, the NW Frontage Road loop is on both sides of the I-84 Freeway. From either direction on I-84 the two Exits #17 will put you on NW Frontage Road. You need to get on the South side of I-84 heading East on NW Frontage Road. After driving by the Chevron, McDonalds, etc. and two large truck-stop style filling stations, go right (South). Proceed past the Outlet Mall entrance and across the bridge over the Union Pacific RR (UPRR) - only 1/4 mile or so. When you get over the UPRR bridge make sure you are in the left lane at the light. Turn left at the light and drive through downtown Troutdale while taking note of the posted speed, crosswalks and all the pubs, restaurants and shops. Just stay on that road for another 1/2 mile after leaving the downtown area. The RV entrance/exit into/out of the RV park is on the the South end of the RV park. When you see the RV park entrance you will see that narrow bridge about 100 yards in front on this same road. There is room for two large RVs with toads in the RV park's driveway. We suggest unhooking the toad there in the driveway. The check-in office is at the end of the driveway. This explanation is way too long given the ease of getting to the RV park from the freeway. Visit Google Maps and it will become quite clear.
We have our own onboard satellite TV, Verizon wifi, shower, etc. Thus we have little-to-no experience with the RV park's services.
The two center rows are pull-thru parking spots. Our coach is 45 feet - with toad 72 feet - so I have always told them when I made reservations that the coach does not make short turns. So we always were given a pull-thru spot that was on the West side of the center two pull-thru rows.
On the NW corner of the RV park there is a bridge that has a weight limit. RVs don't use that bridge, but once the RV is parked most people use the bridge for easily entering or leaving the RV park in their toads. If you walk to downtown Troutdale, then use the bridge. Downtown is only a few hundred yards past the bridge.
Important: Make sure you do not park your toad on the "street" between the pull-thru parking rows. The local fire marshal will ticket your toad if it protrudes out into the "street" - $150 if I remember correctly. The whole RV park is concrete and grass. The pull-thru is concrete and the toad parking spot is concrete beside the RV pull-thru spot. I was told by someone there once that the fire marshall awakened him in the middle of the night to hand him his $150 ticket and waited for him to move his toad.
Good luck... and welcome to the rainy side of Oregon. We live in Hermiston about 190 miles East on the fair-weather side of Oregon.
