the only hotel I ever stayed at was the Marriott at LA Live which is the closest to the convention, and some sessions are also held at this hotel. I am not sure whether it is the best …. after all, you expect quite a bit for the price. But to me it is the most convenient because it allows running up to the room in between sessions, dumping off purchases.
Look forward to seeing you at IDEA World 🙂
I think you need to choose depending on your budget and your expectations. I can only suggest good service where you can compare prices and see a lot of reviews https://planetofhotels.com/en/north-america And decision is up to you.
