M&M World on the strip is a must stop during your Vegas trip. There is 3 or 4 floors of nothing buy M&M memorbillia, furniture, toys, games, trinkets, and they even have a movie theater. There is fun for all ages, and surely something for everyone to buy. You can even buy and mix your own color combo of M&M's. It's a fun stop for me, because I collect M&M items for my daughter who is nicknamed M&M.
