Are you planning to connect to the internet while in Cuba?
If so, Would you like us to pre-buy a WIFI card for you?
They cost 3/hour.
You can get a 5h card, at $15, we send you the codes via email so you already have it when you arrive.
This avoids you waiting in line 1hour or getting fakes from the park ;)
The card is useable at any etecsa hotspot on the island, and you can connect and disconnect as many time as you need so the 5hours last your entire trip.
