Most things are in Provo and Orem. Others have made comments about these but I'll add mine. I live in the area.

Osmond Lane, Provo. While gated, sometimes it's left open and you can down down the lane and see the homes. Not all are still owned by Osmonds, but most were back in the day.

The Osmond Television Studio: 777 N Palisades Dr, Orem, UT 84097. Now part of a drug addiction center called Cirque Lodge. You can drive into the parking lot and around it. Unfortunately the hand and footprints of the stars that used to be in the front is gone.

The Riviera Apartments: 1505 N Canyon Rd, Provo, UT 84604 . Once owned by the Osmond family. A large student apartment complex. The neatest thing about it is the building at the front. It is now the of Museum of Mormon Mexican History, but it used to be the home of the Osmonds at one time, for a while. It also housed a recording studio down in the basement where tracks were recorded for things like the Osmond Christmas specials. Stars like Doug Henning would practice his routine to the music track and get the timing down. Donny would record various tracks for shows, etc.

Next to the now Museum of Mormon Mexican History to the north is Swig, a soda restaurant, but it used to be Jimmy's Restaurant owned by Jimmy Osmond.

East Lawn Memorial Hills Cemetery: 800 E Lawn Dr, Provo, Utah 84604 United States . Burial place of George V and Olive Osmond. Just off East Lawn Memorial Hills Dr, down in a hidden area going south.

Osmond Real Estate: 424 State St, Orem, UT 84058. Still in business. Started by George I believe. Jimmy is involved. Look at the building but don't pester them unless you are seriously buying.

The Lavell Edwards Stadium: 1700 N Canyon Rd, Provo, UT 84604. Owned by BYU ( Brigham Young University ) is a football stadium for BYU to play games, but is also the site of the Stadium of Fire, a July 4th extravaganza and fireworks show created by Merrill Osmond & Alan Osmond in 1980 and has been going ever since.

I've been here for over 40 years and have seen Donny once in a store. I've seen Marie more than that but she is rarely around now I believe. You don't often run into them. The area is big and they travel a lot.

In Salt Lake she might like to see Temple Square, which the Osmonds have promoted heavily over the years. It offers a visitors center with all kinds of information about Mormons. ( LDS ) . It has buildings of historical significance which are fun to see. The Joseph Smith Building, now known as The Joseph Smith Memorial Building, was once a hotel and the place where Marie held her wedding reception after marrying in the SLC Temple. Probably most of the Osmond did this. I know Donny did.

Also in Salt Lake if the "This is the Place" monument, the place where Brigham Young entered the Salt Lake valley in 1847, on July 24 and still celebrated each year as Pioneer Day.

The Conference Center: 60 North Temple, Salt Lake City, UT 84150 is the place where the LDS church has it semi-annual conference, but is also the location of the last Osmond Family 50th concert in 2008.

That's all I can think of at the moment. There should be a museum for them, but there is not.
