I think that in your case you clearly needed thst support with the sunbeds with 2 kids with really complex needs.
As a mother of a son with complex SEN I think it incumbent on us to only use support when really needed and just manage when not. So I would not require a sinned to be reserved. My DH goes down at 6 and has an early swim and sits in a bed for an hour or so reading whilst I get DS ready to get out ( which is a bundle of fun!) We then meet him at sun beds and have breakfast.
We do have issues with sunbeds if they are not located in a peaceful area but sometimes that can work in our favour as the ones that are less popular can be the most peaceful. We have to avoid loud noise and crowdedness etc. On of us always has to supervise DS so we don’t need to be near a pool as we are usually with him. In essence we play pass the parcel with him. Often we can’t stay out at 11am and after for a few hours as it’s too noisy. It can get quite miserable as one of us used to have to stay in the room to supervise DS but now he is old enough to be alone. DH would time it to do his work ( he always works on holiday ) so he would set up phone conference at about 11 am. Nowadays we can pay extra and get a swim up room or room with a balcony and splash pool.
However when w have stated in a really noisy hotel and they had a ‘privileged’ section we have had to ask if they could help and they permitted us into the quieter pool. They have done this and we were really grateful. The holiday would have been a complete disaster otherwise.
We do use the fast track airport support only because if we have to stand in a queue DS paranoia means that he thinks that people are trying to take his id looking at his passport. Also since we ended up shutting down the queue when DS was younger and almost having to have all bags taken off the plane - long story. We were told to always use that service and have done so, I have heard people talking loudly ‘we had to pay for fast track ….etc’ I tend to ignore it but I my head think ‘You want to get him boarded first trust me.’
So saying we try to push DS to manage what he can manage, When TUI messed up long haul seating and DS had to sit near strangers they wanted to separate people and allow DS to sit next to me. We had called to sort out priority seating / disability seating but it got messed up. The crew had a pre flight meeting to try to sort out the situation and decided to move people. Instead I asked the people this names and about them and then introduced son and said ‘this is John, he’s a teacher and likes History ….’ DS could then cope and they were lovely to him. He also had the sense of achievement sitting next to strangers.
Sometimes if things go wrong then it can be awful and I wonder why I even bother going on holiday eg if we don’t get fast tracked through the security at the other side and DS starts freaking out etc.
Overall I have found most people really kind. The swimming pool I’m at people always give up spaces to try to accommodate him near a quieter edge - I say no he’s ok but his visibility is actual visual despite being classed as ‘ invisible’. He looks ASD complex needs etc. At the poll there are younger professionals who seem well educated and generally aware so can see DS disabilities if that makes sense eg mannerisms.
Sadly a posh really well known middle class gym were absolutely rubbish and failed to help at all. They wanted him to share a lane for a 1:1 swimming lessons we paid for him. Older intolerant people. complained as he splashed too much when swimming. ( he has low tone and struggles with his limbs eg his stomach sinks on a crawl and he uses more arm strength), Ironically we got the lessons to stop him splashing but realised that there was no way forward. swimming lesson in a shared lane would have been a waste of time as DS has a profound fear of touch.The biggest irony was that some of the older would swim backstroke flailing the arms and legs around, occupy an entire lane and stop anyone else using it etc. Some swam so slowly that even slow lane people could not use that lane but they deemed it their right to do so, Pot kettle black sprung to mind and what was more galling was that many were paying a lower monthly fee than us. They did no realise how much accommodation was made for them but begrudged any accommodation for DS and instead made my life hell and we were paying the club £5000 a year for that including swimming lessons
So we had to leave but we are thousands a year better off going to a cheaper gym/ pool with lovely people so it worked out well.
