When visiting Río Grande, it's helpful to know a few practical tips to enhance your experience. First, WiFi is commonly available in hotels and some public areas, but you might find it limited in more rural locations. If you need mobile data, consider purchasing a local SIM card at retail stores along highway PR-3. This will keep you connected during your stay. Charging infrastructure is generally accessible in hotels and shopping malls, so you can easily power up your devices.In terms of local customs, tipping is appreciated, typically around 15-20% in restaurants and for service providers. Dress codes are usually casual, but remember to reserve beach attire for the beach areas; more formal attire may be expected in upscale venues. A friendly greeting like "Hola" goes a long way in making connections with locals. Lastly, while tap water is generally safe to drink, many travelers prefer bottled water for convenience. Don't forget sun protection, as the tropical climate can be quite intense. Sunscreen and hats are recommended for outdoor activities.
