I apologize if this is an improper post and please delete if necessary. Anyway I am arriving in Vancouver, late May, with the wife after a Celebrity cruise from Alaska. I have all my reservations and departure plans in place. I am looking for some help in some things for example I will probably visit the Van Dusen garden should I acquire some $C to buy tickets or use my Visa card or $US? This question will be pertinent for restaurants and shopping etc. I am viewing the Youtube videos on what to do. What looks good is the Capilano bridge park, Gastown, Canada place. I am open for suggestions. One of my concerns is weather and it is always unpredictable but is it somewhat warm in late may? Being from Kauai 60 degrees  is cold to me and is rarely ever that cold except in early am. Should I bring some silver maple leaf for barter? TIA for any help.
