Two Strip resort properties with connections to Las Vegas tragedies are observing significant anniversaries Saturday, but corporate owners aren’t planning any special events to mark them.

Representatives of Caesars Entertainment Inc. said nothing special is planned at The Cromwell, which will mark 45 years of operation on the northeast corner of Flamingo Road and Las Vegas Boulevard.

Farther south, MGM Resorts International has no celebrations planned for the 25th anniversary of the opening of Mandalay Bay.

A Caesars representative said a bigger observance may be in store at The Cromwell later in the spring when the 188-room property marks 10 years as a Caesars property on April 21.
