The Ikos is on the edge of a small fishing town that has very little going on, although you can get the bus to Cala d'Or or Palma. There is one two-star hotel and five or six restaurants (some, if not all, of the board options at the Ikos include having dinner at some of those). The beach is small and (like all beaches in Spain) public, despite the attempts of the Ikos to pretend that it's private by putting their own sun loungers on it.
There's no need for two centres in Mallorca, which is the size of Essex. You can get around by bus for the odd day out. (Or, if you have an Ikos-sized budget, you can probably afford to go by taxi.) In Palma everyone goes to the cathedral, which is spectacular, but there is also the castle and Genova caves.
Puerto Pollensa is lovely, but so is Puerto Sóller. A less-known place that also has a bit of real character, but not many UK visitors, is Colonia Sant Jordi.
From (Puerto) Pollensa you can take a great day trip to (Puerto) Soller. Get the 231 bus over the mountains (an absolutely spectacular trip), then the old wooden train to Palma, and the regular 201 bus back. Or do that in reverse.
If you do take the wooden train, here's a tip. When the train pulls in to the station and the arriving passengers get off so you can get on, follow the locomotive as it shuttles round to the other end of the train, and as soon as it gets hitched up, go through the door into it from the last carriage. There you will find the first-class seats (comfy chairs and sofas), for which there is no extra charge.
