SuzieHi
Have visited most of the Canaries over the years…….. many apartment holidays and hotel holidays.
South Tenerife- Adeje area would be best in Dec. due to best climate(usually). You can walk for miles along the coast on good footpaths. Lots to look at, beaches & scenery, and many restaurants and bars to enjoy. Weather usually warm & sunny during the day- jacket or jumper eve.
Look at the hotel Colon Guanahani- adults only (4*) quiet hotel with great food & 5 mins from beach and coastal path & shops ( Tui offer it)
We tend to book flights ourselves, then choose 2 hotels we fancy & do 4 nights in each! (Packing is easy when there, & a short taxi ride is all it takes? ). Rui Arecas also nice for a few nights in Adeje. If you want 5* luxury go for the GF victoria or the Riu Palace or Jardines de Nivaria- all in Adeje.
Fuerteventura- Corralajo best seaside town(in my opinion). Might be windy/not so warm in Dec.
Lanzarote- Playa Blanca best resort but cloudier and cooler than Tenerife in Dec
( usually)
Gran Canaria- Puerto Morgan warmest sunniest spot with most character. Rest of Gran Canaria- disappointing/ overbuilt/run down in my opinion. Haven’t been to Melonores the newest area yet- may be ok?
La Palma- nice island but cool in Dec!
I second Colon Guanahani, stayed here in March went with Jet2. Lovely hotel, adults only, very low key not much entertainment but you can go over to the sister hotel Jardines de Nivaria for a change.
