Holiday Inn Diamond Bar
Our weekend getaway!
We arrived on Saturday it's a quaint hotel with all the eneminties new rooms, relaxed atmosphere we decided to stay an extra day it wasn't until checkout on Monday morning I requested a late checkout 12:30 max nothing major but I was denied because it was a booked day and apparently my room was booked that was the only flaw I did not engage very well with especially being a rewards client, we travel lots for business so we live out of hotels that was the first time ever I'm denied it didn't feel good not sure I'll be back.

Before booking, No pool patio area
Like the renovations for the property. Would of like to of known that the patio & pool area was out of service before I booked. Had to change plans for family gathering. I still would of booked the stay but would of had family meet at another resturant area.

I’d stay again
Nice hotel. A bit loud due to the freeway right there. Staff was really nice and the bar area was too.
