BTW, who the hell needs to have hold baggage going to Spain? The weather is good, ye don't need much clothes.
Or wants to buy their toiletries / suncreams before they leave, and that may want to bring some back if they are not all finished. And those with a little dignity that would like more than a couple of changes of clothes for the evenings.
See the same people leaving the hotel each night for a week / fortnight in the same clothes??? Must've flown Ryanair!! Lovely...
Each to their own, but like I've said before, just because they're cheap doesn't necessarily make it good value. I'm sure we all don't buy food in Lidl, Aldi or buy Tesco Value. Sometimes it's money well spent to buy the odd thing from M&S!
