For one of the routes we are booking in Vietnam, everyday up until the end of March is really cheap - £30 - but then they go up everyday to £50 from 1 April onwards for many months. Is it too early to book and that price is likely to go down, or is that just their 'summer' pricing kicking in?

(I realise the difference is small so not a big deal, but I'm helping to arrange this for a group who are really budget-conscious to trying to lower their cost!)

Thanks
