We highly recommend renting a car!! It will give you more freedom to enjoy the area. Also, ubers and taxis are sparse in North Tahoe.
Everline Resort is at 6,200 feet above sea level. It will be extremely important to stay hydrated to avoid altitude sickness. Also, be aware that alcohol will hit you much more intensely at this elevation (1 drink = 2 drinks). There will be many open bars throughout the weekend, so just remember to pace yourself!
The weather is extremely variable in Tahoe at this time of year. Think typical mountain vibes - cold in the evenings and warm in the sun. Definitely pack layers! It will also be dry so pack extra lotion, chapstick, and eye drops!
Welcome party is "mountain chic" attire. Which essentially is just a fun way to say dressy casual. Think sundresses for women and a button down shirt and pants for men. Wedding day is where the action is at. Please dress in cocktail attire. Also bring a light jacket! We will have heaters but it gets cold when the sun goes down.
We recommend staying at Everline Resort as this will be by far the most convenient option. However, there are also Air B&Bs throughout the area if you want to stay with a group in a cabin.
