Download and keep a copy of the DR e-ticket and check immigration requirements before you fly — many travelers on Reddit reminded others that the e-ticket is needed for entry and that failing to check requirements can cause problems at airports.
Choose your base wisely
Punta Cana is primarily resort-focused (great beaches, limited town life). If you want more local atmosphere, consider Las Terrenas, Cabarete, Sosúa or Bayahibe — these get good recommendations for beaches and town life.
Transport: buses and shuttles are an option
Long-distance coaches (Caribe Tours and local coach lines) connect major towns and are commonly used; buy tickets at terminals. For transfers from smaller airports or remote peninsulas, expect taxis, shared transfers or private shuttles — plan/price them in advance.
Be cautious about renting and driving a car
Many commenters advised against driving unless you’re confident: roads can be poor, driving style aggressive, lots of motos, and insurance/claims can be difficult. If unsure, use taxis, shuttles or buses instead.
Safety: be smart and localize risk
Overall many travelers said tourist areas are fine but exercise normal precautions: avoid walking alone at night in unfamiliar urban areas, stay on-property in isolated resort zones if advised, watch belongings, and treat travel advisories as one input rather than definitive ground-level conditions.
Plan island and beach trips in advance
Isla Saona, Isla Catalina, Cayo Levantado and Playa Rincón are popular day trips. Book tours, check schedules and budget accordingly; some remote beaches (Las Galeras/Playa Rincón/Frontón) are highly recommended by visitors for scenery.
Health, money and practical tips
Don’t drink tap water in many places; bring sunscreen and basic meds, and consider travel insurance. You’ll see prices in Dominican pesos (they often use the $ symbol) but US dollars are commonly accepted in tourist areas — carry some local cash for buses, markets and small vendors.
