what if aides and bodyguards had their own families to take care of as well?...
Send their families too. Sen. Cruz has plenty of money. And, recall he and his family were looking for people to go along. There might be an issue of people NOT wanting to leave ("have to watch my property", etc.), but that's solvable with a little organization & resourcefulness. Ted is supposed to be a leader, right? Organize neighborhood watches & get a little positive publicity from that...? Most problems are also opportunities.
Send one from D.C. Ask another Senator. (Etc.)
Good Lord, FR is supposed to be a repository of people who exude initiative and self reliance and I get asked questions like this?
