Beth,
We've been to florida in November for the past couple of years and you can get some good deals if you just hang fire for a bit!!
It may be an idea to ring up a couple of consolidators from the Teletext as you may get a good deal even now. We paid £340 ad/£200 child for last November (booked in Jan/Feb) but if we'd have waited I saw flights being advertised for £140 through
www.choiceair.com. But if you realistically budget for approx £250 - £300 adults fare and approx £180 kids (scheduled). We ended up going indirect in November but that was because we wanted to go from Manchester but even so it wasn't such a bad flight and to keep costs down I'd definately do it again.
Actually I've just searched on ebookers.com for Nov 10 for 2 weeks and the flights are coming out at £282 each inc tax or £262 inc tax on expedia.co.uk (they are indirect though).
As Bev mentioned you can get a condo quite cheaply and we used Stateside in November and had a fantastic villa. The community pool/Club house is great at Windsor Palms and if you rent a condo you are right opposite the pool, they also have a small 64 seater cinema/grocery shop and a fully equiped gym. If you want to keep costs down then I'd stick with the condo, we've always gone with a villa because of the pool option but you end up paying approx £70 - £100 per week for pool heating (and spa if they have one) and that certainly bumps the cost of your holiday up. The other thing we found going in the later months was that we hardly used the pool as we were out and about in the day and by the time we got back it was dark (and cold!). It's a different story in the summer because of the light nights and longer park hours as you can visit the park, come home for a swim and then return to the park in the evening. You can't really do this with such short opening hours (imo!!)
You'll be able to hire either a economy car for £126 or compact for £140 per week.
Based on the above it's coming out at £1624 which is a little over budget but that's booking it now, if you are prepared to wait a little longer you may be able to get your flights slightly cheaper.
Good luck
Lisa
