The DR requires an E-Ticket form, filled out only at the official website: eticket.migracion.gob.do.

The form is completely free! Don't be like Patrick, who somehow paid $40 for nothing. Watch out for scam sites that charge fees.

Fill out the entry form before check-in and again when leaving. Take your time because the site is far from perfect and will test your nerves.

The Dominican Peso (DOP). USD is also sometimes accepted in tourist areas.

Where should I exchange money? Use a local bank or ATM in the city. Banco Popular and BanReservas are reliable. Avoid airport exchange booths.

In most of the world you look left or right when crossing the road. In the DR you need to look left, right, up, down and behind you. Some Dominicans tend to drive like lunatics so expect the unexpected and be extremely cautious when on or next to the road.

As might be expected, you can’t drink the tap water, but brushing your teeth with it is fine.

Bring DEET repellent (30% +) as Dengue fever is present year-round.

The main numbers to save are 911 for general emergencies, 809-200-3500 for the tourist police (POLITUR). POLITUR specifically assists tourists and has English-speaking staff.
