Pool Pass Value Check: Should You Buy a Pass?
Use this quick math before buying. Daily admissions will not be credited toward a later pool pass, so decide before paying for several single visits.
Resident family of 4
Pass price: $278. Daily family cost at $10 each for four people: $40. Break-even is about 7 full-price family visits.
Non-resident family of 4
Pass price: $377. Daily family cost at $15 each for four people: $60. Break-even is about 7 full-price family visits.
Individual resident
Pass price: $115. Daily adult admission: $10. Break-even is about 12 full-price visits.
Decision rule: if weather, travel distance, schedules or children’s interest make 7-12 visits unlikely, daily or twilight admission may be safer.
Step-by-Step: Plan the Right Oasis Visit
Daily admission is for one visit, twilight is for 6:00-8:00 pm, and a pass only makes sense for repeat visits.
Pre-season, full season, holidays and post-season weekends do not all use the same hours.
Low temperature, storms, safety hazards, special events or very low attendance can close the pool.
Proof of Niles residency is required for any eligible person 17 and older to receive resident rates.
Use lined swimwear, swim diapers where needed, approved life jackets only, and avoid coolers, glass and outside food inside.
Children under 12 must have an adult 18+, and children 5 and under should stay within arm’s reach.
Decision Cards: Which Option Fits Your Day?
Pick by time, weather risk, child age and number of expected visits.
One full family day
Best fit: daily admission.
- Good for first-time visitors.
- Use if children want slides, splash pad and diving-board time.
- Call first if weather is questionable.
Short evening swim
Best fit: twilight admission.
- Runs 6:00-8:00 pm.
- Cheaper than daily admission.
- Not ideal if children need a long play session.
Repeat summer plan
Best fit: pool pass.
- Pass holders can enter one hour before the general public during eligible periods.
- Not refundable.
- Buy in person at Howard Leisure Center for new passes.
Young kids or cautious swimmers
Best fit: shorter visit with active adult supervision.
- Start with zero-depth pool and splash pad.
- Keep children 5 and under within arm’s reach.
- Use hourly safety breaks for snacks and sunscreen.

| Children 5 and under | Parents are responsible for keeping them within arm’s reach. | Supervise from inside or directly beside the water area. |
