Marina

We stayed 2 nights with Aloft in El Segundo. The hotel is absolutely pet friendly and there is no pet fee. They provide you a doggy gift upon checkin: cookies for the dog, a toy, wipes and pop bags.
You can access most of the places in the hotel with the dog (except pool area). They also provide bikes free of charge so you can bike with your dog to Manhattan beach area (although the dog is not allowed on the beach).
To sum it up - absolutely recommend.
