This has been said to us now more than once by friends. One of whom we didn't believe had the means to actually follow through so we sort of blew it off with a very non-committal "oh, okay, sounds great." Then a couple we are quite close to but unable to invite due to budget said this as well and I almost fell out of my chair. What do you say to someone who says something like that?! Obviously the resort is a public place and we can't dictate when or where our friends (or anyone else) vacations but this has left me feeling really uncomfortable. If they do actually make the trip to Mexico I would feel compelled to invite them. But that strains our budget and doesn't leave us in the best position financially to add to our guest list. I've heard of self-inviters before but we figured a DW out of the country would sort of help eliminate that type of issue. What to do!?
