Takoma has a parking lot. There's not dedicated parking at Roosevelt or Marie Reed (w/ Roosevelt probably having a bit easier neighborhood parking). Also, if you're gonna drive, Turkey Thicket has a parking lot and might be worth adding to your mix.

Roosevelt is a school pool and not a parks one. It used to be open only outside school hours but I think that changed. Might be worth swinging by but being prepared with a backup pool in mind.

As to facilities.

Marie Reed redid the locker rooms and deck a few years ago. It's nothing fancy but a relatively clean, new pool these days.

Likewise, Turkey Thicket redid the locker rooms a few years ago. Again, nothing fancy but clean enough (bonus they have a hot tub if you used that at Wilson).

Takoma is a distinctly larger pool. I've not been since it recently reopened, but it was redone (and had nice locker rooms beforehand). Previously it was short course configured with a bulkhead between the diving well and lap swim area, which meant it was a safe bet even when programs were going on.

Roosevelt is a pretty standard high school pool. You share the locker room with the school. The deck and lanes are in good shape and it's one of the less crowded pools I've been to (though I usually swim in the evenings!) Sometimes you get youth programs, but they tend to stick in the two lanes that are not for lap swim (this can be a pain if you're in the last lane, but generally never has been an issue for me).
