A few more festivals...

A few festivals near here:

Hastings Comedy Festival 10th-16th June: https://www.hastingscomedyfestival.com/   This festival has been running for a few years now and has plenty of comedy shows in various venues around the town.

A pottery festival takes place at Glynde Place 10th-12th May: https://potfest.co.uk/visit/potfest-glynde-place/  Glynde Place is an Elizabethan Manor House in the village of Glynde which is open to the public on certain days in May and June (see their website for details: https://www.glynde.co.uk/) They also hold concerts. You can take the train from Bexhill to Glynde and then walk 10 minutes to Glynde Place (I've never done this so I can't vouch for the route. It looks straightforward, just one road - Lacys Hill - but I don't know if there is a pavement or how steep the hill is.)

Glyndebourne - A must for opera lovers since 1934: A purpose-built opera house in Sussex, just outside the village of Glynde. The setting is fantastic, everyone dresses up to the nines, elaborate picnics are partaken of in long intervals (or there are indoor eating options), and the opera is world class. Their summer season runs May to August but they also have other events through the year. Glyndebourne is just 45 minutes' drive from here. They do run a coach from Lewes station (4 miles from Glyndebourne) at a cost of £10 return,  and Bexhill is on a direct train line to Lewes (48 minutes) so you could enjoy some champagne with your opera picnic!   https://www.glyndebourne.com/
