Both are very nice. Northstar is more difficult to book since Hyatt has very few units there. It is basically a ski resort but has many summer activities. High Sierra is near the lake and may have more availability in June. That said, any summer week is difficult to book in Tahoe. If you’re trading internally within Hyatt you’ll probably be successful. If it’s an external trade, not so much. Also, there are some rentals on Redweek if that interests you.
