we are currently in colombia as part of a large south america trip and have just booked flights to cuba arriving in 3 weeks time. We are visiting family who are also visiting cuba and will spend a week in Havana with them, so we will have about 3 weeks to see the rest of the country. As this is not a huge amount of time and we do not like to rush and prefer to see less places and spend more time, I was hoping those of you who know the country well could direct us to 4 or 5 must see places. We are budget travellers so will look to stay in casa's rather than hotels. We would like to visit one really nice beach location (just for swimming and relaxing - not diving) and the other 3 or 4 a mixture of small towns with colonial/old charm and any great nature spots (hiking).
Other questions I have is we have HSBC bank cards from Hong Kong with 6 digit pins - is this likely to be a problem? if so should we bring hard currency (is eur better than usd there?)
Is it worth travelling by train or is viazul a better alternative?
If we needed to take an internal flight is it better to organise in advance (as in now)?
We are australians and my understanding is we ask for a tourist card when checking into our flight - do we need to pay for this?
really appreciate any advice
