I've been going to Hedo solo for a long time. I don't think there's really a 'season' when there are more of less singles. Regardless; singles are always welcome and included in everything. Just my observation, for whatever that's worth.
Thanks Denny for your Grand Lido resort section on your website. It gave me a much better picture of all the goodies we have in store for us. Last December at Hedo good friends also shared their very positive experiences at GLN prior to the WWW winter 2018 gathering.
I always use a kindle and have had no problems. Of course, a regular Kindle (as opposed to a Kindle Fire which is just a tablet) does not have a camera. I would never use a tablet with their glare problems. The "e-ink" of a Kindle works great. At some resorts, I read in the pool, so I have a Kindle Oasis because it is water-resistant. I think it is good down to 10 feet or something like that which works for me. I have never tried floating in the ocean at Hedo while reading.
I have the 2020 "rack" rates. But these are the higher base rates that they calculate sales against. The 2020 sale rates should be out in a day or two. At that time, I will get back to those that requested 2020 quotes.
