Yes, I know it sounds cliche, but Canada has exceptionally polite citizens. You can engage almost anyone who speaks English in polite conversation. British Columbia has the friendliest customs agents (WA State Border Patrol Excluded) they were fast, efficient, even apologetic. I remember once flying back into the USA I thought I had accidentally broken the law and was gonna get arrested just because one customs officer was having a bad day.
Maui is wonderful and for the most part the aloha runs free, but being a haole on the “valley isle” comes with a certain amount of “stink eye” as my friends call it. Vancouver on the other hand is extremely ethnically diverse. Everywhere you walk your ears are bombarded with different accents and dialects. It fosters an air of acceptance and anonymity. I hate feeling like I stick out. My only complaint is a complement of sorts, for a big city everyone stares and talks to you. I had one homeless man tell me I had a million dollar smile. On another occasion a Jamaican Jazz player stopped mid song to tell me I was gorgeous and deserved a rich white man. It took me a while to adjust to this, but if you embrace it, everyone has fantastic ideas for where to stay, what to see, and where to eat.
Canada’s amazing tourist bureau runs specials in late October that include low fares and cheap hotels. I’m an extremely cautious traveler. The best part about solo female travel to Vancouver is that you feel safe, it fosters such a relaxing environment, I felt free to wander around its many parks and downtown areas, pumpkin spice latte in hand. I would highly recommend it for anyone needing a few days to get away. The “solitude” was the much needed recharge that I was seeking.
