Sounds fun, but your schedule confuses me.
You are changing to the Coast Starlight early in the morning at Sacramento, which makes sense: you are omiting an overnight connection.
BUT you are also taking the Empire Builder to Seattle, as opposed to Portland, which means that A) you are overnighting in Seattle, and incurring an unneeded off-train overnight, but making an uncomfortably early (to me) connection to avoid an overnight in San Francisco, one of the most interesting cities in the country. Why?
It also means you are not going to have the Sightseer lounge for the last day of your Empire Builder routing.
If I were you, I'd change it to:
Silver Meteor - orlando to dc
Capital Limited - dc to chicago
Empire Builder - Chicago to Portland (same-day connection)
Coast Starlight - Portland to EMY (Overnight in the city by the bay!)
California Zephyr - EMY to CHI
Finally, from this point, Do NOT take the Capitol Limited again!
Instead, take the Cardinal, and connect to the Silver Meteor.
