Okay, I talked to a supervisor. He said they Coast Guard inspection is definitely being done on tomorrow's sailing, April 2, and there will not be one on April 23. He said he's not sure why we got this text message but it could possibly be a glitch. So apparently the text message is real, even though I had never gotten one from them before. He thinks they sent a text due to the fact that the Coast Guard inspection is for tomorrow and since the date was so close, they sent a text rather than an email.
