Your room is big and void of color. Yes there is too much brown. If not replacing. Add light colored pillows big in a cream print. Add teal to mix. Get a 8 x10 area rug. Go cream base and a contemporary design in very bold colors, red, yellow and black, teals mix it up. Can you get regular chairs. Those look like game chairs, can they go in kids room? Pull sectional into room out of corner face TV wall. With big rug and a 36" ottoman square. In a color. Maybe zebra for fun. On TV wall. Get a wall to wall floor to ceiling or close to it wall unit. Ikea has some go white. Get. Long low media cabinet. Also Ikea in white. Place TV on top. Fill wall unit with colorful pots candles books. Just don't over do leave 50% empty. You could paint that wall a darker (2) shade of walls. After you have centered sofa in room more. On wall behind a very large art contemporary 40x40 hang very low. On empty wall in dining area. Get a long 6-7 ft chest. Something different. Asian feel red lacquered would be fun. Over it add big art piece bold colors 40 x40 hang 6" above top of cabinet. More art big by dining table. I would change chairs to a high back leather in Teal. Pier one has them. Your whole place needs color. Area rug under table 8 x10. Solid teal. Add big palms in corner to fill and warm up space. In chairs get two swivel barrel type in a print. Modern go taupe and blue/greens. Wi Dow panels on ends only in teal. Ck bed n bath. TJMax a good source. For art ect.

Center the bed between wall sconces. You have many, many beds in your ideabook that will be a great inspiration for dressing the beds. You need king size pillows, 2 or 4 depending on how much you are spending on redecorating a hotel. How many rooms will you be updating? I would get a nice natural fiber woven waste paper basket to put the plastic one into. I would get a more comfortable desk chair, and definitely more substantial curtains in a neutral color. Are there supposed to be drawers in the bottom of that armoire? If there isn't, I would add runners and drawers to it for storage. Perhaps slide the desk/armoire down towards the power/Internet/cable access. Sheets, crisp white, light color neutral blanket, between two flat sheets, neutral coverlet over that. If needed, a duvet in a white, bleachable duvet cover. For color a dark or bright bed scarf that spans the end of bed, nothing too wide. Piece of art over bed that reflects the locale or nearby sightseeing spots, or an abstract that references the color of bed scarf. If doing a floor covering, keep it neutral and easy to clean. Not sure what color walls are, but they could do with some brightening, a nice bright ivory color would still be warm and welcoming, but would add light to a dim room.

Have you ever thought about floating shelves? I think pairing a few floating shelves together would look great and would free up space in your living room. I really like the Eugene floating shelf from Bryght and I think it would compliment your existing pieces. http://www.bryght.com/product/160/eugene-cocoa-shelf

You could do plain velvet curtains in the same light pinkish cream of the sofa. To add some drama you could have a nice patterned sheer curtains in blackish grey. Place an area rug, below the centre table, install some nice candle holders on the wall in metallic tones. Place a runner diagonally on the centre table and place a nice Buddha figurine, with votives on both the sides of the Buddha. Add some elements of green by putting a few plants, palm or dancing bamboo as it's easy to maintain. Add a few lamps to set the mood and look.
