Nice one, we've since booked up elsewhere for this year but will definitely look to return to Menorca again, especially whilst the kids are young. i love taking them down the little beach coves rather than some packed beach you'd get in mainland spain/majorcia where you fighting for every inch of sand just to lay a couple of towels and kids can wade really far out and the waters still only waist deep. Beautiful island.We've been to Cala en Porter a couple of times mainly due to the airport proximity. The second time we got a car and travelled around a bit and the only place we weren't keen on was Cala Galdana. I probably wouldn't stay on the North coast as the weather can be a bit rough around Fornells.
we were quite close to Cala Blanes first year we went, some lovely villa's up there.Rented a villa in Es Castell / Cala Fonts last summer and had a great time
