I booked a bedroom and a roomette on the same overnight Amtrak train. The bedroom is worth the splurge for longer rides.

I've taken two overnight train trips aboard the California Zephyr.

The California Zephyr is a double-decker Amtrak Superliner train that runs between Chicago and Emeryville, California.

The train has coach cars with regular seating and sleeper cars with private cabin accommodations — roomettes (the lowest tier), bedrooms, and bedroom suites (two joined bedrooms). There are also larger, family-sized bedrooms and accessible bedrooms.

First, I stayed in a roomette for a 15-hour trip from Colorado to Utah.

For the shorter journey from Denver to Salt Lake City, I booked a roomette for $400. With two seats and two beds, the roomette sleeps up to two passengers, though I was traveling alone.

Then I booked a bedroom for a 53-hour trip from Illinois to California.

I booked a bedroom for the full journey from Chicago to Emeryville for $2,200. The bedroom is roughly twice the size of a roomette and also includes a full bathroom. The bedroom also sleeps two, but again, I was traveling solo.

The roomette was a 23-square-foot private space.

Inside, there were two seats across from each other, with a fold-down table between them. The only floor space in the roomette was the gap between the seats. I couldn't imagine being comfortable with another passenger in there.

At 50 square feet, the bedroom was more than twice the size of the roomette.

The bedroom had a couch and a seat facing each other, with a table between them. I appreciated having a couch for the longer trip because I could stretch out and relax during the day.

I also liked that there was a bit more floor space in the bedroom.

In the roomette, the two chairs folded down to form a lower bunk.

The bed was cushy and wide enough to snuggle up comfortably.

In the bedroom, the couch folded down to form a cot that appeared to be slightly wider than the roomette bunk.

The lower bunk in the bedroom felt more spacious than the one in the roomette.

Both rooms also had a top bunk that pulled down from the ceiling.

Since I had two nights in the bedroom, I spent one night in each bunk.

The bedroom had a full en suite bathroom.

Inside the bedroom, there was a sink and vanity with a built-in cabinet where I found hand towels, soaps, toilet paper, and space to store my own toiletries. The toilet and shower were in a tiny space separated by a door.

For two nights on a train, I was thankful to have my own shower.

Roomette passengers shared a bathroom and a shower with other sleeper cabin passengers.

Since I only spent 15 hours in the roomette, I didn't mind not having a bathroom in my room. I didn't use the shared shower; instead, I washed up once I arrived at my destination.

The bedroom had more storage space than the roomette.

Each room had a mini closet with two hangers inside, as well as a shelf that appeared to be for storing luggage. In the roomette, the shelf was only large enough for my backpack, but in the bedroom, it held my carry-on suitcase.

On both trips, I also had access to shared luggage storage space in the train car.

The bedroom also had a larger mirror.

Both rooms had mirrors, but the roomette mirror was shorter and thinner. So I appreciated the wide, full-length mirror in the bedroom. It wasn't just convenient for getting ready — it also made the space feel larger.

Both bookings included meals.

Passengers had the option of eating in the dining car or in their rooms.

I think I booked the right room for each trip.

The bedroom served me well for the two-night journey, and I would splurge on it for any Amtrak trip 24 hours or longer. I think it's worth the added price for the extra space and full bathroom.

At the same time, I'm glad I booked the roomette for the 15-hour journey. It was a short trip compared to other overnight rides, so sacrificing some comforts and privacy to save money was a good move for me.
