Hi Rob, take US cash and travellers cheques, the exchange rate is the best it's been in a long time and I don't think you will get pesos here in England anyway. Don't change them at the hotel, they will rip you off. Is the Tropicale the Fun Tropicale at Playa Dorada? If so, you can go to the plaza and change them at the bank there, they will give you a much better rate. Alternatively, if you are out and about use the cambios in Puerto Plata, Sosua, Cabarete, or wherever you are.
You won't be cold in the evenings, trust me - I'm English so I know
