Pros:
* Outstanding course design - demands mostly accuracy, is balanced lefty/righty, rewards a broad disc skillset
* 5+ pin positions for each of the 19 holes, with every hole changed each Monday
* Perfectly maintained grass, teepads, benches, signage
* Attractive urban park setting
* Elevation change on most holes
* Two pin positions mounted atop wooden pyramids - a creative touch
* Well stocked pro shop with discs, food/drink, apparel, open from dawn to dusk
* Located close to family attractions in Balboa Park, such as the Zoo/museums
* Pay to play - a pro because that income pays for 5-7 employees who staff the pro shop, mow the grass, put down woodchips, fix benches, rotate pin positions, etc
Cons:
* Does not have many, if any, holes that allow big arms to let rip with a driver(depending on pin positions)
* Crossing fairways in four areas(holes 3/4, 5/6, 11/12, 15/16/18/19)
* Busiest disc golf course in the world - if you don't play at certain times(see guide under Other Thoughts), you will experience waits like you never thought possible
* In most configurations, plays on the easy side for Blue players(-2 to -6 average) and almost trivial for Gold players (-8 to -12 average)
Other Thoughts:
This is the course where I was introduced to the game, and my parents' home is a mile from the course, so I play several times a year when I'm visiting San Diego. Many players will ding Morley for the insane crowds, and it's true that waiting behind multiple groups of 6-8 players, clad in flip flops and carrying more cans of light beer than discs, is detrimental to your mental health. If you play early in the day, however, you can avoid this experience and get to enjoy what is a very good disc golf course. Bring a towel, because the grass is often freshly watered.
Here's my visitor's guide for weekdays and weekends if you want to beat the crush. Check morleyfield.com in advance to see if there's a monthly tournament or other event taking place, because that may alter the following advice!
Weekends/holidays:
Dawn to Dawn + 1h30m : parking available up front, course flowing and mostly open
Dawn + 1h30m to Dawn + 2h30m : front parking lot is full, course is busy but playable, only waiting for one group/hole
Dawn + 2h30 to 1hr before Dusk : Sixsomes, girl scout troops, so many players waiting behind each tee it looks like a picnic
1hr before Dusk to Dusk : Course loosens up some, if you bring running shoes you could almost jog a round throwing through groups
Weekdays:
Dawn to Dawn + 3h : parking available up front, course flowing and mostly open
Dawn + 3h to about 1 pm : front parking lot is mostly/completely full, course is busy but playable
1pm to 1hr before Dusk : Pretty awful, but not as bad as weekends/holidays
1hr before Dusk : Course opens up some
