North Goa has big trance parties and more of a backpacker/budget traveller scene. Goa is all about cafes, restaurants, bars, clothes stalls, markets and miles amd miles of relatively unspoiled beach. There are still active fishing villages and local communities mixed in with the resorts of differing styles and sizes. You can hire mopeds or motorbikes (if you are experinced confident!) to explore inland Goa too or arrange excursions to the ever expanding Anjuna Market, to some waterfalls, to Old Goa's catholic churches etc. If you want a wide range of eateries and something like watersports on offer then pick one of the larger places such as Calangute, or Baga. From Palolem you can go on Dolphin watching boat trips. It depends what appeals to your children - one recommendation - stay somewhere that also has a pool, sometimes the hawkers on the beach can disturb your beach time by persistantly trying to sell you stuff - mind you fresh fruit and cold drinks can be welcome, but it is nice to be able to retreat to the pool and if your kids don't like waves. On some stretches of beach the waves can get quite big somedays. I really enjoyed watching the local fishermen hauling in their catch by hand whilst dogs stood by to run off with the fish that escaped the net.
