School holidays can be a mini nightmare at times in London.
During holidays queues are longer etc. due to the volumes of kiddies out and about. Easter week is also slightly manic, as are bank holidays.
We last went to Kew Gardens in April 2006, and I was in a really long queue, and there is generally no queue, you can usually just walk in through the gold leaf gates!
But it's their busiest day of the year (Easter Sunday). I started at 60metres, that's what the line beneath my feet said. Took about 40 minutes to actually get into the park though.
I wont go again at times like these!
Well, of course there will be some plants in full bloom and some plants that are past bloom so pay attention to the leaflet they hand you when you entrance to see what you can skip.
The azaleas, magnolias and rhododendrons were all past bloom so the middle section of the garden could have really been skipped but since I was on foot there was no avoiding it.
