My sister lives near Barcelona and it snowed last week , wouldn't count on it being particularly warm in Feb (lovely though). Southern Spain might be better - Granada perhaps? Ryanair have just started flying direct there.
Or what about somewhere like Marrakesh? still not too long a flight.
Charley I agree with MrsFP - DH and I had a fantastic holiday in Marrakesh before dd. Loads to do - really great shopping, some truly fantastic restaurants and places to stay and lovely, warm sunshine.
Now I've written all that down I'm thinking I might try it with my lot.....
I know you mentioned not wanting to go massively long haul, but dh and I went to Barbados when I was 24 weeks pregnant and it was great. Rang BA beforehand and told them I was pregnant so they allocated me a bulk head seat with loads of leg room - flight was only 8 hours and didn't feel too bad at all. Went to an all inclusive sporty type place - so DH spent then entire week waterskiing, playing tennis, sailing, etc. whilst I relaxed on my sun lounger in semi-shade reading books or was in the spa getting massages, reflexology, facials, etc. A really excellent holiday - would definitely recommend it.
Someone in RL suggested Madiera a while ago - I'd forgotten, so that's another one to check.
I'm not sure if I have the energy at the moment for Istanbul, I'd love to go at some point in the future though - it's the sort of place I'd like to take a kid, I think they'd find it fascinating!
Ooh handbag - you've got me thinking now! Thing is, I'd like to go somewhere like that for at least a fortnight, and dp's only around for about a week (shouldn't really be taking any time out at all! )
