While I am at the conference in Utrecht I will have an Air B and B apartment and after that I am theoretically spending 4 nights in Tournai and 4 in Antwerp.
I had a more economical place to stay in Antwerp (the ‘t Stadhuys Grote Markt) but heard it was very noisy and so changed to the Rosier10, at that address (Rosier 10) Antwerp 2000. In Tournai I am at Apart’hotel Le Dix, Place de Nedonchel 10. Like the Antwerp hotel, this one alludes to its address in its name.
This means that with tax I spend almost $1,000 in hotel costs for 8 days, and this is being done because I no longer tolerate bad lodgings as easily as I once did. The reason I am staying in Belgium is that my return flight is from Belgium, and I am trying to save on the cost of travel elsewhere.
But for $1,000 I could fly to Riga and back, and stay somewhere comfortable for less than in Belgium and be better humored if where I stayed were not comfortable. I could go to Mitau, and to the beach at Jurmala.
I should do it. Now, the cheapest flights are an illusion since they do not allow for luggage, so it will really cost about $400 to fly back and forth. This would leave $600 for lodging, if we take the $1000 figure to be accurate, and perhaps I could do it for less.

I like the Art Hotel Laine and the St. Peter’s Boutique.
I can go to the beach. I have seven nights; I could stay in both of these hotels, starting in one and coming back to the other after, for instance, a night or two at the beach.
(Or do I really want the beach? It appears that it could be expensive. Go for the day?)
If I go to Jurmala then the hotel would be Villa Joma.
And a backup in Riga is the Rixwell-Gertrude.
And of course there is the Albert hotel, named after Einstein.
Three days of fancy hotel, two of beach, and two of art hotel could do it. Or: two fancy, two beach, and three of art, but I think the former is the thing — I’ll see, first I have to commit to the ticket.
