Wow congrats on these fine events! It sounds like 2024 has a lot in store for you. For sightseeing, the whole west coast is pretty fantastic. I've seen only a small part of it, but Big Sur, the sequoias, Oregon coast, etc. are absolutely mind blowing. Point Reyes seashore (north of San Francisco) is terrific for photography. Lots of great wildlife, especially bobcats. In my neck of the woods, Banff & Jasper in the summer are crazy busy of course, but if you plan ahead you can get to the prime attractions with shuttle buses. June is also a great time for bears.
