Las Vegas is open for business, though it may not be business as usual.

Amid coronavirus and protests, the Las Vegas of today won't be exactly what millions of prior visitors remember from their days in Sin City.

"Good Morning America" outlined last week some of the changes visitors are likely to see Thursday and into the foreseeable future. Among them: fewer people at gaming tables, additional hand washing stations, temperature checks and more frequent cleaning of high-touch items, like dice.

Still, there seemed to be plenty to celebrate as casinos began opening just after midnight. According to ABC News affiliate KTNV reported "hundreds" waited to enter the D Las Vegas.

Many hotels and casinos have a 10 a,m. local time opening planned. But The D Las Vegas and Golden Gate Hotel and Casino, both downtown, opened at 12:01 a.m. CEO Derek Stevens told "GMA" his employees are "excited to go back to work."

Properties are welcoming visitors back in a variety of ways. Sahara Las Vegas is waiving resort fees for the month of June. The D and Golden Gate -- which previously offered 2,000 free flights to Las Vegas -- offers a free bottle of Tito's vodka to anyone who missed a birthday celebration in Vegas. The promotion is good for guests who book a room throughout the month of June.
