Maybe we were there on an off night but we felt there was a lack of show and engagement at the
Disneyland Trader Sams, it was honestly a little boring and the space is pretty small so it felt a little cramped to us.
As for the pools, we used the main pool and its awesome, very comfortable chairs and easy to get a spot (atleast for us in August when we were there last), plus the restaurant there is good for a quick bite to eat.
It’s a little bit of a hike to get to the main entrance to the resort (when compared to Grand Cal lol), so the monorail is great to take you right in to the park. Without that, some of the hotels on Harbor are almost as close if not closer so at a fraction of the cost it’s easy to justify staying off site IMO.
