Enjoyed this exercise and some questions

Question

This was a fun exercise. I really enjoyed learning about la montee des marches and seeing the beautiful photographs of Cannes while researching the vocabulary.

My question refers to the "hotel de luxe". Since the "stars" are plural wouldn't one assume that they leave their "luxury hotels", (plural)? Which would be: "leurs hotels de luxe" ? Or, is the possessive here always expressed in the singular, "leur hotel de luxe"?

Another question is about the use of the present tense in "j'admire". Would it be incorrect to say, "...que j'admirais depuis toujours"

Merci beaucoup !!

Bonjour N. Hilary,
Thank you for your kind feedback! It is always nice to hear such positive comment.
- In French, the use of "leur / leurs" is different to how you use "their" in English. Here you can have both "leurs" and "leur" - See the links here for further explanation: leur lettre or leurs lettres    -   Leur-Leurs
- J'admire / J'admirais: 
Using Le Présent shows it is an ongoing activity that is still happening in the present of speech (equivalent of the English Present Perfect).
... que j'admire depuis toujours = ... whom I have been admiring for ever
If you had L'Imparfait, it would refer to an ongoing situation in the past: 
... que j'admirais depuis toujours = ... whom I had been admiring for ever
Because the main verb is in Le Futur, L'Imparfait doesn't work here. To have L'Imparfait here, the main verb would have needed to be "J'allais voir..." = "I was going to see..."

I hope this is helpful.
Bonne journée !
