It sounds like a great trip!

I checked the campgrounds (for trailers) inside Yosemite valley a few days ago and they were booked through July 15th except for a few, one-night dates (reservations aren't available yet for dates after that). There are a few campgrounds outside the valley that you might want to check out, but it can take quite a while to get into the valley if you camp outside. There was also a slide that has been blocking one of the roads so you might want to check the NPS website for information on that.

If you can't get into the valley with the TM, you can probably stay for one night there with a tent without reservations; there is a campground just for people who want to spend one night there and then take off hiking the next day.

It might also be possible to get into one of the Valley campgrounds (if someone has cancelled) if you just show up with your TM. Timing your arrival there midweek would probably increase your chances.

I would imagine that Sequoia also gets booked way ahead of time, so you might want to go ahead an make those reservations now if they're still available.

We've been to Yosemite in June, September and October, and June was the best great time to go. There were horrible mosquitos though, so bring your repellant. And bring your rain gear for hiking; the spray from the falls can drench you in about a minute.

Have a great trip!
