SixFlagsSuperCalendar

What This Is

A personal website that consolidates theme park operating calendars into a single full-month grid view. Starting with all Six Flags parks scraped from their website, expanding to any theme park via configurable scraper adapters, and eventually becoming a trip planning engine that suggests nearby parks and estimates travel costs.

Core Value

One place to see every park's open days — so planning a trip takes seconds, not a dozen browser tabs.

Requirements

Validated

(None yet — ship to validate)

Active

Full month grid calendar showing open/closed days across all Six Flags parks
Web scraper pulls park hours from sixflags.com (URL pattern: /{park}/park-hours?date=YYYY-MM-DD)
Scraper adapter architecture so other park chains can be added with minimal new code
Any theme park can be added via manual configuration (URL pattern + scraper adapter)
Trip planner suggests nearby open parks given a target park and date range
Drive time shown between parks
Rough flight cost estimate via Google Flights for farther destinations

Out of Scope

Booking / ticketing — just planning and discovery, not purchasing
User accounts — personal use, no auth needed
Real-time wait times or crowd levels — calendar/hours only
Mobile app — web-first

Context

Six Flags park hours follow a consistent URL pattern: https://www.sixflags.com/{park-slug}/park-hours?date=YYYY-MM-DD
Other major theme park chains (Cedar Fair, Universal, Disney, Busch Gardens) have similar site structures — a reusable scraper base should cover most cases
Trip planning example: planning King's Dominion → surface Busch Gardens Williamsburg as a nearby park that's also open
Google Flights rough estimates (not bookable) are sufficient for V2 flight cost

Constraints

Data: Web scraping — no official API, fragile to site redesigns; mitigate with adapter isolation so fixes are localized
Audience: Personal use only — no need for scalability, auth, or uptime SLAs
Tech: Website (browser-based); stack TBD during planning

Key Decisions

Decision	Rationale	Outcome
Scrape over API	No public Six Flags API exists	— Pending
Adapter pattern for scrapers	Different parks have different HTML; reuse parsing logic where possible	— Pending
Personal use (no auth)	Just for the owner; no user management complexity	— Pending

Evolution

This document evolves at phase transitions and milestone boundaries.

After each phase transition (via /gsd:transition):

Requirements invalidated? → Move to Out of Scope with reason
Requirements validated? → Move to Validated with phase reference
New requirements emerged? → Add to Active
Decisions to log? → Add to Key Decisions
"What This Is" still accurate? → Update if drifted

After each milestone (via /gsd:complete-milestone):

Full review of all sections
Core Value check — still the right priority?
Audit Out of Scope — reasons still valid?
Update Context with current state
