Congrats dude! Definitely personally recommend going in the spring- especially if you wanna avoid the crowds as it really gets quieter after spring break is over and like previously mentioned, the weather can be nicer and more predictable too (... but its also the PNW and the weather does whatever the hell it wants). Going before spring is obviously awesome too, but is more of a gamble weather and snow wise. Main village is more of a "downtown" vibe to stay in with lots going on, Blackcomb/ upper Village is calmer and a short walk or free bus ride to the main village and also has some really boujee spots to stay at if you wanna impress the lady. Creekside's village is the quietest and least touristy if thats more your vibe, but is a bottleneck on busy days as thats where Vancouver skiers tend to park and upload. My fav places to eat/ hangout: Rolands, Creekbread, Stinkys, Handlebar, Samurai Bowl, La Cantina, RMU and then Crystal Lounge for cheap wings. Sushi Village is a legendary spot too. Both mountains have a good mix of greens and blues, but blackcomb tends to have more decent sized sidehits to keep ya entertained outside the park. Happy to help w anymore questions you've got, lived in whistler for many years
