The Peace Arch is fine if you are going to stay at Peace Arch RV, otherwise you are better to use Pacific Highway/Blaine border crossing (where the big rigs cross) From there you can get onto the 401 West and take that all the way to Taylor Way Exit (WestVan) and down Taylor way to the Capilano RV park. Yes, minutes to everything. Aldergrove is a bit East of Pacific Highway, but it is fine to cross as well, access to the 401 just as easy.
If you are travelling from Peach Arch RV, stay away from the Hwy 99 rush hour as it is gridlock and no matter what time of day you travel, traffic in Vancouver City and across the Lions Gate Bridge is heavy.

If you have the time, check out Whistler (where olympics were held)
