What's inside

Why GPT-5 changed the maths

What's actually new compared to GPT-4 and Claude (context, reasoning, multimodal) and why hospitality felt it first.

Hotel-grade prompts that work

Prompts for upselling, late-checkout handling, OTA replies, multilingual welcomes, and review responses you can deploy this week.

Guardrails and accuracy

How to prevent hallucinated room rates, invented policies, and other classic AI failures in guest-facing channels.

The integration layer

Where GPT-5 fits in your existing stack: PMS, inbox, webchat, WhatsApp Business API.

Measuring the win

AI resolution rate, response time, CSAT, ancillary lift: the four metrics that actually matter.

90-day rollout plan

Week-by-week plan from sandbox to full property, including staff training and escalation rules.

Built for hotel teams, not engineers

Front office

Stop answering "what's the WiFi?" 40 times a day. GPT-5 handles the routine in 50+ languages.

Revenue & marketing

PMS-personalised upsells and re-engagement on the channels guests actually open.

General management

Standardise service across properties, cut OTA dependency, and shift the booking mix towards direct.
