Yes, laying on a beach towel (and last time I checked,
DCL doesn’t provide beach size towels) is completely normal- what’s not normal is paying the Disney premium and not getting the Disney service.
I can go to my local beach for free. When I’m paying extra for Disney, it’s because I want the Disney service and that includes safe and easy accommodations. I don’t want to need to carry a beach chair across dunes so I have a chair to sit in to watch my child swim (And saying the chairs are light is relative. Similar to how some guest struggle with the pier)
When the larger ships are at LP it looks like you have to be there very early to get one of the oceanfront chairs. I’m not talking about people who stay an extra hour or two on the ship once it’s docked not finding chair except behind the dunes.
If DCL wants people to go ‘sitting on a beach towel’ route, they could at least provide beach towel sized towels, not just bath sized they currently give out.
