dont know if you have already booked now?? we used to stay at the guaryamina princess and thought it was great. however, it was taken over by thomson about 5? years ago and it became like a holiday camp with activities going on all the time which made the place seem less relaxing and more rowdy. it depends what you are looking for. if you go on holiday reviews website you should get more of an idea. some hotels in adeje we have stayed in: hotel costa adeje supposed to be 5 star but definitely not and consensus of lots of people, restaurant food is poor and the carvery service so slow, like a canteen. anthelia park fabulous but pricey, costa fanabe dingy, needs a refurb and mouldy sunbed cushions, bahia del duque 5 star and luxurious, would cost you a fortune for an extended stay but worth a try for a treat at some point, jardines tropical a bit germanic though very nice and in a nice spot, in las americas, in laws went to bouganvillea, said it was good, in los cristianos the arona gran is the best one for us, looks out over the harbour, again pricey i would imagine for a long stay. the vulcano as i already said seems the best buy and has a good write up. let us know what you have decided and happy extended! hols. lucky you!!
