Notes and quick tips

• Offerings and schedules change seasonally; many tours are arranged through each hotel’s concierge and may be complimentary, hosted by partners, or paid — confirm price, group size limits and meeting point with the hotel before arrival.
• If you want, I can look up specific tour schedules, current prices, or concierge contact info for any of these hotels — tell me which hotel(s) you want more detail on.
