Who is the supervisor?

The names below come from the operator. Each links to a page of what public sources say, with the sources.

Worth asking the operator

  • Who signs the kashrut certificate for this program, and can I see this year’s certificate?
  • How many years has he supervised this operator’s Pesach programs, and this hotel in particular?
  • Does an agency or beth din stand behind the certificate, or is it his personal hechsher?
  • Is he in the hotel for the whole of Yom Tov, and how many mashgichim work under him?

Getting there

There is a nonstop flight from New York (JFK), about 7 hours in the air.

Lisbon lists year-round nonstops from all nine cities; London is served from Heathrow, Gatwick, Luton and Stansted, and Paris from Charles de Gaulle and Orly.

Most North American travelers fly nonstop to Lisbon from the East Coast or Toronto, or connect once in Europe.

Routes come from each airport’s published route list, checked October 2026. Flight times are estimates from the distance. Airlines change schedules, so confirm before you book (route list we used).

From the airport

  • Lisbon Humberto Delgado Airport (LIS): about 35 minutes by carLisbon's main airport, linked to Cascais by highway.

Late April weather

Mild and often breezy, with highs around 66°F (19°C) and nights near 54°F (12°C); the Atlantic is about 61°F (16°C), cold for swimming.

Good to know

  • Portugal is five hours ahead of New York.
  • The currency is the euro.
  • US passport holders do not need a visa for a short stay, but check whether the European ETIAS travel authorization is required by the time you travel.
  • A car is handy for Sintra and the coast, though Cascais also has a direct train to Lisbon.

Safety and travel advisories

What governments say about travel to this country. Nothing here is this site’s own judgment.

US State Department travel advisory for Portugal

Level 1 of 4: Exercise normal precautions

  • The level is for the whole country, not for the hotel or its neighborhood. Level 1 is the lowest of the four and Level 4 the highest.
  • Advisory dated December 22, 2025; I read it on October 4, 2026. Levels change, so open the advisory before you book and again before you fly.

This is the governments’ own wording, not a rating by this site. Israel’s National Security Council also publishes travel warnings for Israelis abroad. Ask the operator what security the program itself arranges, such as guards and entry checks.
