I've always found the Rio shuttle to be very convenient. Two shuttles, one to Bally's and one to Harrah's. They ran frequently and they never completely filled up (Sunday through Thursday, I've never taken it on a weekend). But now they have just one shuttle. To Harrah's. And just one vehicle. We took it from the Rio at about 5:45 tonight and the line was long. Returning from Harrah's about 11 the line was even longer. About 3 shuttles worth. I'm assuming they will have more than one vehicle on the weekends but maybe not. They also now require riders to be TR members. They had staff at the Rio going through the line and signing people up if they weren't members. They were given temp gold cards. However, coming back the driver didn't check for TR cards. I talked to a guy at the Rio and he said having just one shuttle is a "test". I think they're just cutting costs. And a lot of people didn't like having to sign up for a card as they stood in line. Personally I have no problem if they want riders to be TR members to take a free shuttle. But having just one shuttle and having a much longer wait makes this shuttle no longer the great service it once was.
