It is a race against time and in my opinion, it is not certain that the albergues who previously accepted a tent will do so with the reopening, and vice versa.
But staying on topic, as it is the situation currently, it certainly could give some small advantage, considering however that not all albergues have the adequate and suitable space, If those who place the tent in the courtyard / garden manage their general needs only and only in that space. But since, at least in my experience, there is a need to take a shower, there is a need to wash clothes, there is a need for a good coffee and a beer, the risk of coming into contact with the other "guests" remains! And maybe for you who chose to camp in a tent, there was no initial imposition to take the indicated sanitary and hygienic measures (at least most of them).
A dog that bites its tail?
In my opinion, the schemes would skip.
From July onwards it will be seen how the situation will evolve.
